Male Nipples & Masturbation
Lots of men do not know how sensitive their nipples are. When I masturbate, I stroke my cock with one hand and twist my nipples with the other. Without twisting nipples I find little pleasure in masturbation. I have found many ways to excite my nipples.
When my wife has a period, I ask her to suck my nipple while I stroke my cock. It is absolutely wonderful to cum while she is sucking my one nipple with her one hand and twisting the other nipple with her other hand. When I am alone, I suck my nipple with a plastic tube that I slip onto a tapered stem of plastic cap (cap is from a glue or other plastic bottle) which is placed on my nipple. The pleasure is absolutely awesome. While I suck my nipple and stroke my cock, I imagine having sex with a lady and finally cum after about 15-20 minutes.
