I'm having sex with a girl that has a boyfriend(he doesn't know), is it okay to have sex with her best friend

Good grief...it's no wonder there are so many unwanted pregnancies, STD'S and above all...AIDS...

GROW UP......

grow up!!!!!!

yup, as long as the girl and her friend are together at the same time.

What does your conscience tell you? Would you want this to happen to you if the tables were turned? Regardless of your decision, don't be foolish and use protection!

yes it is very good because sex is your right

YES - you should write a book, and be my guru

u can bang whoever u want, all girls are horny and borned to be banged. also what i wanna say is, no matter how long we are going to dicuss here, u'll still going to bang her friend anyway. no one can change ur mind. so go ahead and have fun! :)

No, because it is immoral

Uhh...
That is called "cheating" to the rest of the world; there's nothing illegal about it, but it's very immoral. I would say stop, and just end it there.
