Like you just said, they are just joking, making fun of her, and
teasing her only. No harm done, so dun get heat up on these minor
minor stuff, you think too much eh bro. Anyway if your gf can
handle it, why not you?
And as for your topic "relationship = sex", well.... I can only
tell you one word : Eventually.
And if you can't take this kind of pressure, you dun deserve to be
in one, cos sooner or later, you'll use this "topic" to stir up a
heaty conversation with your gf. The aftermath.... just use your
imagination.
Besides, she's your gf... not your dog. Wat right have you got to
restrict who she can or cannot befriend with? But no harm sounding
out to her about your unhappiness and let her sayang abit.
Anyway, if I sound harsh in anyway, I beg your pardon.
