How to act straight after 6 bottles of Tequila

There was a party held by people from work. The organizers were a bunch of 20-somethings that at some point worked at the bank, and their parties are known for being a booze fest where only a few can say they didn't woke up the day after with a huge hangover (and lots of regrets). When I was invited, I was a little doubful about attending, for several reasons:
I get really..uhm..."festive" when I drink. And by festive, I mean loud, intense, and sometimes obnoxious. And since everybody there were going to be people I'd have to see next monday at the office, I didn't want to be vulnerable of doing something embarrassing.

I'm also very..."flirty" when I drink. And by flirty, I mean I look at people I feel attracted to like a lion watches its prey right before going after it. And, being in a room full of straight bankers, having that attitude probably wouldn't be a good idea.

Eventually, I told myself not to be such a girl, and decided to go. I mean, being afraid of acting stupid or gay (or both) wasn't a good reason for me to avoid having fun and meeting new people.

I arrived early, so I had the chance to talk to some of the poeple I already knew, who then introduced me to most of the people who showed up later. The first hour was just us talking about work, life, etc. Small talk. Then we all had some fajitas (It was a mexican themed party). Then, the heavy part of the party started. There were about 25 people, and as far as I know, 6 bottles of Tequila and 2 of Aguardiente were consumed during the party. I didn't get drunk until I realized I had drunk more Tequila shots than I can remember, which was way after most people did (I still have a little hangover, which was why I couldn't even smell alcohol at a friend's birthday party last night).

In the end, It was great. I did have some embarrassing moments (there was some singing, some flirting with a guy and then with a girl , and some african-colombian music dancing I regret) but overall, it was nice. Photos of the party still haven't been posted on Facebook, so I don't know how things will look on those...I hope nobody took a picture at the wrong time and make me look like a total drunk...I don't photograph well :-)

What pisses me off is getting nervious every time I have to face a large group of people, being afraid of people telling I'm gay just because the way I talk, or the way I move my hands, or any other thing...which only makes me act like a total social inept. I guess that's what's important about taking an internship, not only practicing what I've learnt at college, but also facing the work environment, and everything it implies...including, maybe, my fear to homophobia.
