Gay or straight has nothing to do with it. I have a male therapist and trying to explain to him what it feels like having sex with a man or a woman, is nothing he will ever experience... Not like I have ...so in the end does it really matter? What matters is the therapist accepts you for who you are. There are many people out there who have tried both. In the scope of things your experiences are our own no matter who you see, all you can do is explain and hope they understand.
