So here's the situation, Internet. I'm a male university student taking a summer field course at a scientific research facility in a small town many hundreds of miles and several state lines from home. Also on this trip is a girl from another university whom I've been spending a lot of time with, both when doing our course work and in our free time. We met and started hanging out together by chance, just thanks to the two of us traveling here on the same bus, but as it turned out we actually have a lot in common and get along really well.
This girl is made of eleven kinds of cute and hot and I want her so bad it HURTS.
And I have a pretty strong hunch from her body language when we're together that she wants me too (playing with her hair, crossing her legs towards me all the time, touching leg-to-leg under the table when we sit next to each other, etc.)
The only problem is... she's taken. I only know that she is because I overheard a bit of conversation between two other girls in which her boyfriend was mentioned, and I don't know whether or not she knows that I know (are you following me here?). If she does know, it certainly hasn't stopped her from continuing to nonverbally flirt with me at almost every opportunity.
Now here's the clincher: The other day we (meaning her, me, and a bunch of other people in the course) were playing a drinking game in which she mentioned two things (both in a hypothetical context, as part of the game): One was "pretending to enjoy lousy sex to avoid hurting your partner's feelings", and the other was "cheating on your SO while on a trip".
Needless to say, this has just sent my speculations and fantasies running to the redline. Note that although we were playing a drinking game, she said both of these things before having had ANY drinks.
So, Internet... should I go for it? I'm an averagely devious person on the whole, but I've never (knowingly) done anything like what my body and my heart are telling me to do now. Pros? Cons? ....tips?
