Would You Pop her Cherry?

[Cunning Linguist]

So I've been dating this girl since early september and she announced to me the other day that she is still a virgin. In case it is pertinent, she turned 19 in August and I am 23. There is nothing wrong with this girl, no deformities or ugliness, in case you're wondering. She told me last night she wants to bone (not quite verbatim).

This piece of information puts forth a difficult moral dilemma for me.
You see, I like this girl, sort of. She likes me a whole f'n lot. She also thinks I like her much more than I actually do. I enjoy spending time with her, and she's attractive to me, but I don't see this lasting very long. I doubt it lasts until Halloween. I do wish I liked her more, there's just something missing.

This girl likes me much more than she should after only one month. If I pop her cherry, she's probably going to think we're going to be together forever (she's a bit clingy) and tell me she loves me, etc. etc.

So, am I a pussy for not jamming her?
Would you take a girls virginity if you really didn't think it wouldn't last?

PS. Assume you're not a desprit, sex-depraved OOT'iot.
