Cumming from just playing with my nipples

I'll start by coming clean and admitting I have always been in touch with my feminine side and for a long as I can remember have enjoyed occasionally wearing feminine clothes as a turn on.

It was this that made me do things I felt were feminine while masturbating. When I was in my 20s I would often play with my nipples and discovered they did indeed give some sexual pleasure but after some initial playing with them I would always be overcome with the urge to touch my cock and masturbate in the usual ways.

One time though about ten years ago I started to wonder if it was possible to climax with just the sensations from them without touching elsewhere and started experimenting more and more with playing with them. I discovered that as I got more turned on they seemed to respond to more extreme forms of touch. I would start by just touching them softly with finger tips, then rubbing them gently perhaps with some oils and eventually progress to squeezing and pulling them quite hard. A few times I also used an electric toothbrush against them. Each time I tried I was rewarded with getting more and more turned on and a couple of times I think I was close to cumming but always the urge to touch my cock took over and won.

I decided one day I would see if it really were possible and told myself I would not touch my cock. If I didn't cum with my nipples so be it but I would not relent. I started as always with soft touches and some oils and got myself very aroused, them progressed to the more extreme squeezing and pinching and felt the usual urges to touch my cock growing. This time though I resisted and still my arousal built. I realised I was now pulling my nipples really quite hard and loving it as I simultaneously squeezed them.

Then it happened. I felt myself starting to cum. Again the urge to touch my cock was so intense but I resisted it and I felt my cock squirt and I was rocked by a really powerful orgasm.

Coming down I was amazed by how distended my nipples were from the squeezing and pulling but felt satisfied I had enjoyed a new experience.

Since then it has now become a common thing for me to enjoy to the extent that when I have time and want a "special" intense climax I often opt just to play with my nipples.

I would love to hear from other men and women who can climax from just having their nipples played with. It would be nice to know how common or unique this is for both sexes!
