Nipple play for men is an interesting topic. Everyone who has seen gay porn videos has noticed that the guys like to suck and play with the nipples of their partners, left and right. But what is behind this sexual desire? The answer is quite simple. Nipples are sensitive parts of the male body, one of the most sensitive in fact. When a man is stimulated through his nipples, the brain immediately responds with a signal of excitement and desire, leading to increased heart rate and breathing, which in turn causes the release of hormones, including testosterone. Testosterone in the body of men is responsible for the development of muscle mass, bone density and sex drive, so when the levels of this hormone increase due to nipple stimulation, men experience increased arousal and desire for sex. This is why you see so many images of men sucking each other's nipples, it's just so stimulating and exciting. And, of course, who doesn't like the feeling of a smooth wet mouth on the nipple? It's always a pleasure!
