I've been with my bf for 4 yrs, I've brought up the idea of us having a threesome a while ago but idk what he actually thinks about it  and I always have dreams and fantasize about it and I have a female friend that also wants to see what it's like to be with a girl sexually, she's never asked me .. How do I tell her that I wanna try it with her? and how do I tell him that I wanna invite her into the bedroom with us??
