lolol No.
It's played because of male pride. Men want you to be easy, but only with them. Men want you to give it up, but if they think you give it up to everybody, you're nothing, whether it's true or not.
I don't even need 2 hands to count the people I've been with, but I had 1 friend with benefits for a solid 9 months. I fell for him after a while because I'm female lol, but long story short it was obvious he definitely didn't think of me as g/f material, even when including him, I really haven't been with many people at all.
So I'm thinking women do it so you won't think we're whores, not so we wont feel like one. We don't; we're usually effing you for a good reason.
