Try asking here best friend. My gf asked her best freind if she would be into it, and at first her friend was hesitant because she hada bf. Eventually she decided she wanted to. We all made it a weekend thing at the best friends apartment. The other threesome my gf and i had was with her half sister. Now i have to say that was a trip, LMAO. Lately we have been looking to have another one. We have been trying myspace, lesbian or gay clubs, and adultfreindfinder. We have had luck with all three. My gf is picky so we havent decided on one yet, but I'd give those places a try first. Oh and by the way have you gf ask the girls. They will feel less intimidated about the whole thing. Have her aproach them without you around then when they are comfortable she can introduce you and bring you into the conversation.
