Would you ever snog a member of the same even if you were 100% straight?

Just wondering......Cause I have and am not happy about it! (I'm a girl and did it for the 'enjoyment/pleasure' of my guy friends in a club after a lot of persuading. Turns out the girl ended up being my room mate and had a boyfriend...he smiles whenever he sees me...ewww! Well at least all involved were hot! Is it wrong? I'm 18 a college student...I'm thinking now that it's what you do when you're young! But would you? Just wanna get a general thought....
