I'm an 18 year old virgin. Turned down huge opportunity for sex. Twice

[Misfitsbeevers]

Personal info: I am a 18 year old virgin. I want to have sex. Really, really bad. Also don't want to lose my job, but I am really close after getting late like twice a week for a month now.

the story:
Yesterday me and my roommate were at a friends house having some beers(my roommate didn't drink). I've had a few beers, when this girl(about 16-17, really really drunk, a little slutty but hot, about a 7 on a random girl standard,
like 5 by OOT standards) starts hitting on me. We make out for like an hour when my roommate tells me we have to leave cause we both have to get up in like 6 hours to get to work. It's a 90minutes ride home, and he's the only one driving. I ask the girl if she wants to get back to my place. She says she doesn't "dare" (WTF?) but we could get up to her place instead, which is 5mins away. I die a little inside
when I tell her that I can't cause I have to get to work tomorrow, and there's no way I can get from her place to my job with no moneyz the next morning.
We kiss goodbye, I get in the car. 50minutes into the ride home she calls me, even drunker than before, and asks me to get back and pick her up. She's all of the sudden changed her mind and wants to get back to my place for some sweet luvin. My roommate is already pissed off at me for taking so long to say goodbye, and refuses to turn back.
Also the girl sounded so drunk that there's a good chance that she would either a) fall asleep on the way home, or b) puke like [censored]. So I tell the gal that I can't,
says goodbye once again and hang up.

I really wanted to [censored] this chick and there's no way I would have had a chance on her if she'd been sober. But she was so drunk that at the time I felt it would be
"wrong".

Needless to say, today I am in deep regret. No way I'm letting this big of an apportunity slip from me again.

So tell me OOT, how would you have acted differently?
