Well, if we're being honest.......
I have had one same sex relationship.......over and over and over. I had always been curious but afraid. I never acted on it until about 3 years ago when a friend and his wife (who I had also been intimate with before they met and sometimes after) stayed over. When he asked, I didn't say no.
I've turned down more than a few, but must admit there are others that I would not hesitate to be with if (or when) they ask. To me, being intimate with another is more about the other than the intimate.
And yes, after 3 years I am still occasionally seeing my friend and, on other occasions, his wife. I'm strange and not surprised that I would fit into a 30% profile.
