Yes I was 12 too and at boarding school. It was bath night and three of us bathed together each in our oun bath. It was not long before we discovered what enjoyment we could get from wanking our cocks naked together. The cum came a year later
Became aware of and curious about my penis and others when I was 4. Figured out by 6 that rubbing my erection felt good, and was actively, intentionally masturbating by the time I was 8. Dont recall ever experiencing dry orgasms, but had my first ejaculation (just a few clear drops) when I was 11.
I remember my first time as I was 11 my 15 yr old neighbor told me she could make white juice shoot out of my penis. I didnt understand , but agreed to let her try. she told me to get naked and she would too! The thrill of seeing her nude body had me stiring and she took my cock in her hand and said relax it will feel good. Her knelling in front of me looking eye level at my cock pointing at her. after about 2 minutes of her stroking me and me touching her I shot my first big load of cum all over her tits and smooth belly. She told me she had done this with a few other boys in the neighbor hood and would do it to me anytime I wanted. Well it happened many more times. even once with my best friend getting his stroked by her at the same time. we both shot cum all over her. After her mom caught her with another another nieghbor boy it stopped as her mom made her confess to all the boys she had done that to. Needless to say I kept on masturbating and even preformed for my sister and her friend a few times, but thats another story.
i think most of us started masturbating to relieve the pressure of having a hard on most of the day in junior high, not sure about anyone else but i had some Hot teachers and not sure if they were teases or not , short short miniskirts not sure how often i got a glimpse of they're panties and no i didn't see bare nipples but some nipples trying to poke out from they're blouses or dresses. i had three in 8th grade none with big breast but when they leaned over and i saw boobs my cock and the other guys in class no doubt throbbed. my bi side in the gang shower just intensified the problem with my hard cock and i know i wasn't the only one that stroked in the showers back than.
