Being bad could be very good.

I'd help him out of the restroom but I would have my hand on his bicep squeezing his bicep, then I would act as if I'm lossing grip and grab his muscled pecs, just muscle grab... when no one's looking, that's what I would do!

if he's all over me, and drunk, i'd proably take advantage of that to get him to my hotel room (cause i couldn't deal wit him in public can); if he's just a drunk in a public john wit no real notice (action) towards me; i'd have to leave him there; if he is free for all wit any one walking into the john, then i'd proably watch him and what'not action for a second and leave him to it..

I'd be good and give him the ride of his life!

O-M-G. Do I know if he is gay/bi? (Do I care?) God. I would be so tempted to be REALLY bad at the sight of him, but I'd probably wind up being semi-good (like the previous commenters) and hope that he is the one who makes the first (albeit drunken) move -- then it's all good !

And if I were to already somehow know that he were gay/bi -- much more likely I'd be really bad at the outset.

Can you blame me ? :)

OMG this actually happened to my at a Staff Christmas Party. We were in the bar and singing karaoke, and some good-looking stud says he likes the sweater I have on. Later when I am in the john, he comes in and stands at the urinal next to me. He opens his pants and fumbles with his boxer briefs and then stumbles back against the wall mumbling and cussing. I was good and asked "Are you okay buddy?" helping him back to the urinal but copping a cheap feel in the process. His stocking was stuffed to say the least. It felt good to be so bad. Aahh --- holiday memories!
BTW I like the biceps on this guy.

Back in college something similar happened with my roommate; we returned to our room late one night both inebriated (he was MUCH more drunk than I and could barely stand). I helped him to our room and to our second-floor window so he could vomit. I helped him take his clothes off to get into bed; when he was naked I reached around (he was still at the window) and stroked his cock a few times. He got annoyed and brushed me away. I helped him to bed and (thankfully) he never remembered the episode.

Of course I would be good to him and help him in my room. ;-)

I'd be bad and after a little groping and kissing, give him one of my signature good ... no, great! ... blow jobs.
