Hi Rolan. I hope I can be of some help.

I understand your position very well. I'm in college myself, and I certainly understand that "craving." But you seem to me to want that special relationship, based on your language, and that this is your second choice, so to speak. I'd tell you to wait for that special time instead of doing it just for the sake of doing it.

As far as obligations go, you're not obligated whatsoever to have sex with anyone. That is a mutual, conscious decision that two people have to make. If you're not comfortable with the decision, it should be off the table.

Now that being said, you mentioned that you didn't know this girl well...why not change that? You may very well "click" with her aside from just a physical relationship. Why not talk to her a bit, see if you two are compatible dating wise, and go from there? Couldn't hurt.

Anyway, take care, and I do hope I was of some help. I wish you my best.
