i have faced that. i guess i consider losing my virginity is the first time i had sex knowing and chosing to do so. that other wasnt sex, it was me being used by some guy for his kicks. i was a sex toy that time. no, i lost my virginity much later, but i understand how uncomfortable that is.
it is like sitting around and everyone starts talking anything sexual, like they might say, i dont understand how a guy can be with another guy. you think to yourself, i have been, i know what it is like, but you dont say it. you are ashamed that you know those things. besides who wants to spoil and fun conversation among friends by throwing a big serious wet blanket on it? instead, you just smile and go along with it. i think that's okay though. you are being considerate of the others. that should be a good thing i think.
compassion is a light even to the darkest soul
