Not sure

So tonight my friends and I are having a drinking game and mostly what we talked about sexual things, you know, like how far youve gone, what your favorite position, your kink, etc, youve got the idea. Its fun of course, we laughed about it, but I couldnt stop worrying, Are they alright? Are they ever forced? Are all of that consensual? And when it was my turn; Where did you do the most scandolous thing youve done? My mind wander to a guy who jerked off right in front of me in a public transportation when I was in middle school. For the life of me, I thought of a way to tell that story in a fun way, and fuck I know what I could say for it to be fun, but I just couldnt bring myself to. I mean I dont know if I could control my face or if my voice would tremble. I dont have it in me to make it a funny story even though it could be a funny one, I mean I wasnt even touched, I wasnt forced, he just ended up in front of me, and I could tell it like, Do you believe theres this guy who jerked in front of me in my way to (this mall)? Its a public space, for Gods sake?! Imagine how awkward it is for me?! But I just cant. I cant remember it in a fun way. I just felt fucking stupid, like I should wack him in the head or something instead of being confused and embarassed, and trying to pretend I didnt see what he was doing.
