I was about 23 or 24. Straight high school buddy was visiting from nyc. We were dropping hints at it for a while...then he went to the bathroom and emerged with his pants still off, and asked me if I wanted to give him a bj. I told him yes, but he had to take a mini shower first, as he had just gone to the batrhoom. I started, but did not get very far as I sort of got shocked when the precum started oozing, then offerd to jerk him off instead. Made a few more attempts since then, but few and far between. Would be willing to practice on a buddy that I trusted...
