I’m not sure if I should stop hanging out with my friends, or if I should just keep trying. Help!?

So my friend got a bunch of molly and had a party with just all of us friends since high school. Of course My friend Forest, who is hosting the party starts playing porn on his Tv, then next thing I know everyone is making out with each other. Things start getting intense and it’s pretty much an orgy of all my friends. I’m just sitting on the couch watching what’s going on, and being awkward. I am not at all horny and I just want to go home, but I’m def. not sober. My friends notice me being weird and try rubbing my crotch and kissing me, but I’m just not into it. I end up letting my friend pull down my pants and of course I’m limp, but he tries to get me erect with no luck. My friend gets frustrated and yells something to the effect of “ what are you straight now ?” I was literally so embarrassed cuz I can’t let my friends know I’m not %100 gay. I say no, and that I just can’t get hard on molly. Anyway, ever since that night, which was 4 days ago all my friends have been ignoring my texts. I think they are offended that I didn’t have sex with them . Should I even bother hanging out with these guys anymore ? They have sorta been my family since high school and right now I just don’t want to be alone .
