Nipples are filled with nerves making them extremely sensitive sensory receptacles. That’s why nipples are sometimes called the “clitoris of the upper body.” Inside the nipples are nerves called the Meissner corpuscle and a little deeper inside is the Pacini corpuscle, both of which have very important sexual functions.

At the tip of the Pacini corpuscle are layers of epidermal cells with plenty of elasticity set up in a formation almost like onion rings. This makes the nipples extraordinarily sensitive. This is why three in every 24 women who breastfeed experience orgasm, according to figures obtained by U.S. sex scholars Masters and Johnson.

Just as the clitoris hardens when arousal occurs, the nipples become engorged, too. In Master and Johnson’s “Human Sexual Response,” the nipples become erect during arousal. They grow anywhere from 5 millimeters to 1 centimeter, while their diameter increases from 2.5 millimeters to 5 millimeters. This is said to be the result of involuntary movement in the plain muscles (but it sometimes only happens in one nipple).

As arousal winds down and plateaus, the erect nipple shrinks. Or at least seems to, because this is an illusion. Actually, what happens is that the aureole are also enlarged, making the nipples look smaller. When entering the orgasm phase, the breasts also get bigger. They expand by as much as 25 percent. But this only applies to women who’ve never breastfed.

The changes aren’t as pronounced among those who have breast fed. That’s because breasts used for feeding had seen their hyperemia, or blood congestion, functions reduced to a minimum. When breasts reach a certain size, the surface veins start to stand out. Because blood congests beneath the surface, it creates an impression that the breast has become slightly transparent.

Once the orgasm phase has been completed, the breasts deflate again. At this stage, we get what’s called a phantom erection. Moving from the orgasm to the withdrawal stage sees the engorgement of the aureole end and they become wrinkled.

That makes the nipples look relatively larger. The breasts undergo an incredible number of changes throughout the various stages of arousal, but that doesn’t necessarily mean breasts are always sensitive.There’s an old saying that the nipples go dark after childbirth, but it’s nothing more than a fable. Some also say that babies suckling on breasts darkens the nipples. That’s prompted some men to believe that darker nipples are a sign that a woman has had plenty of experience with men sucking on their breasts. This is a complete misunderstanding. Guys apparently have a thing for pink nipples, but color has got nothing to do with experience. The darkness of nipples or genitals has absolutely no relation to sexual experience. If anything, the only physiological reason nipples darken is to make them easier for babies to find.

Breasts and nipples are truly mysterious objects. Women shouldn’t keep them to themselves. Why not get adventurous with them with your loving partner? If you consider it a breast check, you can kill two birds with one stone. Conduct a thorough investigation of the breasts. Check to see whether there are any noticeable changes in the left and right breasts.

See if there has been any tautening of the skin or indentation of the breasts. See if there are any dents or irritation in the nipples. Slide your finger slowly from the outside of the breasts, tracing a line over it to the inside area, touching evenly and checking whether there are any bumps. A bump doesn’t have to be a fully fledged lump. What’s important is noticing whether things are different to normal. That’s also why it’s important to regularly check the breasts and, perhaps occasionally, let your partner help you out at times.
