Is it true that S did'nt loose her virginity to N in the show. If not him, who did she loose it to?

No, she told Dan that most guys never looked at her when they slept with her, and she and Pete seemed to have a sexual relationship before the sex tape bit, So I'm guessing she lost It to some random guy she met at a party

truly i have no idea,but i hope she did lost it to Nate

They never say who she lost it to. It is assumed that she probably lost it to some random, I'm almost positive she didn't lose her virginity to Nate though.

no in the shows they have never said who she lost her virginity, most likely some random guy, in the books it was with nate

i think maybe that guy that she thought she killed in the begining u know that guy that died from a drug overdoce

They don't really say to who she have lost it, but I belive it was with Nate. And in the books it was with him.
