She's setting you up. And if you were any little shred of a real man and had any sincere interest in her or in having a serious relationship, you would decline her offer and not sleep with any of them.
Any woman willing to basically whore you out to her own family and friends only sees you as a toy and piece of meat, not a potential serious relationship (which would make sense since you say she only wants you for friends with benefits).
I keep telling her that I have no interest in her friends and family and that I'm talking to her and her alone.
She just wants to hear how special she is because she keeps bringing it up like a million times a day.
You and that and that girl would be great together let me hook you up bla.
I see a broken girl just entering the big bad world and she's testing me out if I'm anything like the men she has encountered before.
I like the challenge but I'm not sure if one man has the power to make her forget about all the other bad experiences with men she has had.
And emotionally, I noticed the age plays a big factor as well in her lack of understanding.
She knows about the physical world of sex but not the emotional one.
So I think the mystery is solved, young insecure girl setting me up to prove I'm just like all the other men.
