Although it really belonged to this section, I already related my first experiences with docking at
http://home.prepuce.com/index.php?topic=263.0 It happened during my mid teens, i.e. when I was still at school, and I regard it as part of sexual experimentation after the onset of puberty.
I guess most guys go through such a phase. Docking is something which is regarded as a gay sex activity, yet I never thought of it as such at the time I did it regularly, i.e. once a week, for about a year. (I am strictly heterosexual).
From the onset of my puberty I started wanking, and soon did it on a daily basis - often twice a day. I found that my recuperation time - i.e. the time from having a full orgasm, to being able to have another - was about one hour. (Regretably, now that I am older it is much longer)! As kids in our mid-teens we shared our stories and experiences with our (male) friends, and often we would have a wanking session when quite a few would join in. Often we would see who could cum first. At other times we would like to see whose squirt of semen would be the furthest.
One bit of sex-play was measuring to see whose erect penis was (a) the longest, and (b) had the biggest circumference. I am well endowed and often ended up in the higher rankings, but one of our friends - a short, slim guy - beat us every time with his huge penis. Where nobody could beat me, was in the "biggest incease from limp to erect" stakes. When limp, my penis is quite normal (and could even be regarded as on the small side). But as soon as I get an erection, it increases in both length and width two to three times.
All of my friends were intact, and we regarded a cut guy as something unnatural and even abnormal. I still wonder how a circumcised guy can really masturbate, not having a foreskin (unless he uses KY jelly abundantly!).
Having had a high libido, even at college I had to have a regular wank just to relieve the sexual tension (if I could not lay a girl often enough).
What about other guys telling us of their sexual awakening and experimentation during their teens?
