The fact that you didn't immediately beat him up makes me think you're gay.
Tbh, I don't think not doing anything means that OP is gay. It's easy to say that you would do this or that when you are not in the situation, but what you actually end up doing maybe completely different. Yes, He should have stopped him or whatever but OP probably thought that him changing positions would stop his mate touching him up. Its amazing that he didn't .. it sounds like the best friend is probably gay or bisexual.
As to what to do about the situation, confronting him is an idea but by not confronting him then and there you have already made your decision not to confront imo. If you are just careful around him you can avoid this situation in future, and if he does or tries anything again, you should definitely confront him.
CHOP IT OFF!!!!!!
in all seriousness, you should tell your friend.
and why is the thread title 'tried'? he blatantly not only tried this BUT succeeded.
WTF????? He was touching you and having a **** and you didn't do anything??? You must be gay like him.
There have been several threads like this recently, featuring night-time touchy-feely.... Are they giving people ideas?
dont lie, did u enjoy it, did he *** all over ya??
This doesn't sound very legal o_O
Sounds really awkward! I'd just try not to let yourself get into that situation around him again! lol
