My First Time
I was a late bloomer, geeky and a loner. I knew about masturbation intellectually but not as reality. I do not have a very active libido. When I was 15, I decided to find out about it. I lay in bed one night and stroked my penis. It came to a full erection quickly. After stroking for a while, I felt like I needed to urinate so I stopped. Then I started again and eventually felt the need to urinate so I stopped again. Then I thought what the heck and did not stop the third time. When I eventually orgasmed and ejaculated, it was quite a large volume but it did not shoot out but just came out relatively slowly. It was certainly pleasurable.
My penis does not have a sensitive feel so it often takes 20-30 minutes to orgasm and ejaculate. I think this is not uncommon but it is not something to brag about.
I used to masturbate once a day but now it is 2-3 times a week. It is still pleasurable and I have no trouble getting hard within 30 seconds.
