The New Joy of Sex: Part 4. The allure of any size and shape. 2008, based on the works of Alex Comfort and Susan Quilliam. Listen to the podcast at How To Sex. Breasts. “In our maturer years,” wrote Erasmus Darwin, “when an object of vision is presented to us which bears any similitude to the form of the female bosom; we feel a general glow of delight, which seems to influence all our senses, and if the object be not too large we experience an attraction to embrace it with our lips as we did in early infancy the bosom of our mothers.” Breasts are the natural second target, but often the first one we reach. Just how sensitive they are, in men as well as in women, varies enormously, and according to physical state and mood. As with other sexual organs, size is unimportant in relation to sensitivity; if it still creates insecurity, however, fascinated attention is a more effective cure than surgery. Some breasts don’t answer at all, even in the emphatically non-frigid; some answer to extremely gentle touches, some to very rough handling (but they are sensitive structures; don’t let a need for forceful contact get the better of sound common sense.) Going round and round the nipple with the tongue tip or the glans, soft kneading with both hands, gentle biting, and sucking gently like a baby are the best gambits; she can do the same for him. (While there, both can occasionally check for suspicious lumps.) If her breasts are big enough to meet, one can get a surprising degree of mutuality from inter-mammary intercourse. This is a good expedient on occasions when she doesn’t feel like vaginal intercourse. She lies half flat on pillows, he kneels astride (big toe to her clitoris if she needs helping) with his foreskin, if he has one, fully retracted. Either he or she can hold the breasts together; wrap them around the shaft rather than rub the glans with them. It should protrude clear, just below her chin. Intercourse between the breasts is equally good in other positions; head to tail, or with her on top (especially if she has small breasts), or man sitting, woman kneeling; experiment accordingly. An orgasm from this position, if she gets one, is “round” like a full coital orgasm, and she feels it inside. Breast orgasms from licking and handling are “in between” in feel. His ejaculation this way gives her what’s known as a “pearl necklace”; he should rub the semen well into her breasts when he has finished (see semen.) Breasts, vagina, and clitoris all at once make the fastest and most concentrated buildup of sensation once intercourse has begun, for some women at least. Many easily stimulated women can also experience a rather special pleasure from suckling a baby. Nipples. a direct hotline to her most sensitive parts. She says: “Unlike a man’s nipples, a woman’s can have a direct hotline to her clitoris and vagina. A man who can dial this correctly and will only take the time can do anything. Palm-brushing, eyelash-brushing, licking, and loud sucking like a baby can work wonders; the orgasms one gets from these are mind-blowing without detracting a jot from intercourse to come after. Please take time.” He, meanwhile, can get a very special jolt from this, made more intense still if she is actually lactating; male suckling is more of a majority interest than you might think. On him, rather than by him, stimulation is less likely to have an effect; few men can get a nipple orgasm, but try a stiff pair of feathers (see feathers) or very gentle fingertip friction; men’s nipples easily get sore. If the effect seems lacking, assiduous attention over time may help; try gentle circles with a toothbrush. There is no proof in the theory that caffeine creates temporary nipple sensitivity, but it’s still worth a try. Fluctuating hormones before her period can turn sensitivity into discomfort, and if there is itching, swelling, bleeding, or discharge, get it checked out. This applies to him as well as to her. If a partner likes pain, or to test the possibility without putting the question direct, pinch nipples lightly, then harder (never when sore, lactating, or newly pierced.) The aim is a balance of pleasure and pain; after, once pressure is released, the whole body will be achingly sensitive for hours. If this appeals, move to nipple clamps (not clothes pegs, which aren’t adjustable); a linked pair with one on each of his and her breasts also provides a neat accompaniment to any movements that create a gentle tug. When taken off, pinch with fingers, then release slowly to allow the blood to flow back in comfortably. Limit time on such play; 15 minutes is enough. Buttocks. a turn-on in almost equal measure far both sexes. Next in line after breasts, buttocks alternate with them as visual sex stimuli for different cultures and individuals. Actually the original primate focus, being brightly colored in most apes; apparently equally fancied by the Neanderthals, who produced some of the best Stone Age figurines. The buttocks are a major erogenous zone in both sexes, though less sensitive than breasts because they have fewer nerves and a layer of fat, and so need stronger stimulation (holding, kneading, slapping, or even harder beating; see discipline.) Intercourse from behind (see rear entry) is a pleasure in itself, but be careful if she has a weak back. In any position the muscular movements of coitus stimulate the buttocks in both sexes, particularly if each holds the partner’s rear fairly tightly, one cheek in each hand. These extra sensations are well worth cultivating deliberately. Visually, good buttocks are a turn on in almost equal measure for both sexes. Penis. while the penis is emphatically his, it also belongs to both of them. Not only the essential piece of male equipment, even if it is often and expressively described as a “tool,” the penis has more symbolic importance than any other human organ, as a dominance signal and, by reason of having a will of its own, generally a “personality.” No point in reading all this symbolism back here, except to say that lovers will experience it, and find themselves treating the penis as something very like a third party. At one moment it’s a weapon or a threat, at another something they share, like a child. Without going into psychoanalysis or biology, it’s not a bad test of a love relationship if, while the penis is emphatically his, it also belongs to both of them. In any case, its texture, erectility, and so on are fascinating to both sexes, and its apparent autonomy, a little alarming. Like the vagina, the penis collects anxieties and folklore, and is a focus for all sorts of magical manipulations. Male self-esteem and sense of identity tend to be located in it, as Samson’s energy was in his hair. If it won’t work, or worse, if she sends it up, or down, the results will be disastrous. This explains the irrational male preoccupation with penile size. Size has absolutely nothing to do with physical serviceability in intercourse, or; since female orgasm doesn’t depend on getting deeply into the pelvis; with capacity to satisfy a partner, though many women are turned on by the idea of a large one, and a few say that they feel more (see size.) If anything, thickness matters more than length. Nor has flaccid size anything to do with erect size; a penis that is large when at rest simply enlarges less with erection. There is no way of artificially “enlarging” a penis. Nor, except in very rare cases, is a penis too big for a woman; widthwise, the vagina will take a full-term baby. If his penis, whatever its length, knocks an ovary and hurts her, he shouldn’t go in so far. A woman who says she is “too small” or “too tight” is usually making a statement about her arousal levels; she needs time, understanding, and foreplay. Shape also varies; the glans can be blunt or conical. This matters only in that the conical shape can make receptacle-tipped condoms uncomfortable through getting jammed in the tip. Women who have really learned to enjoy sex are usually as fascinated by their lover’s penis, size included, as men are by women’s breasts, shape, odor, and feel, and learn to play with it fully and skillfully. Circumcised or not (see foreskin), it’s a fascinating toy quite apart from its main use. There is a whole play scene connected with uncapping, stiffening, and handling it, making it pulsate or ejaculate, that is a major part of togetherness. This is equally important for the man; not only is it ego-boosting, but good hand- and mouth work practically guarantee a good sexual partner. Care and maintenance: if he isn’t circumcised, he will need to retract the foreskin fully for cleaning purposes, and if it won’t retract beyond the corona all round the glans except at the front, get it seen to (correcting it involves a trifling operation with a blunt probe and doesn’t necessarily mean that he needs circumcising.) If it won’t retract properly or is over-tight and gets stuck, get that attended to as well. Slight asymmetry often develops with time; this does no harm unless it’s pronounced or painful, in which case see a doctor. On the other hand, don’t bend an erect penis or use a position in which it could get violently bent by accident. (This usually happens with the woman on top if she is careless near orgasm, or in putting him in, and he is just short of fully stiff; keep a little control here.) It is possible, though difficult, to fracture one of the two hydraulics contained in the shaft. This is very painful and can lead to pain or kinking on subsequent erection. The normal organ will stand up to extremely hard use, but not to these. (Avoid also silly tricks with suction and so on; see inflators.) Sores, discharge, lumps, bumps, bleeding, and so on signal illnesses and need treatment. Even if you both have proof that you are free of all sexually transmitted d
