I have a gf for 8 months now and I have found many things about her. Our sexual experience for each other is incredibly crazy. We go at it for like 30 mins to hours. We are very open with each other, trusting each other on our everyday decisions. We respect and assist with our daily decisions and feelings. I found out that she is a bi and she finds the same sex beautiful and attractive. Sometimes when I go out with her I check out girls vice versa(which she allows) and when I/her do sees an attractive girl she checks them out and tells me there distinguishing figures. She is very down with a threesome but the girl that I want to do it with, is her friend. :eyes What do i do?
