me and my boyfriend have been together for a long while now and the sex is great, don't get me wrong, but recently we've been talking about having a threesome with another girl. he said that he really didn't want to have sex with her, only to see me and her go at it. that's perfectly fine with me but it's hard to find someone that i can trust. i'm straight but i am curious. thoughts?? i just want to hear what other people have to say!
