I agree with Shazerac. This is a topic just begging to be discussed with your therapist! If embarrassment is the thing preventing you from doing so, perish the thought. Face it; there are few things therapists haven't heard & you have nothing to be embarrassed about.
Perhaps I'm odd, but I somehow always find myself fostering friendships with lesbians while not knowing they're lesbians when I meet them...& I'm a guy! My theory is maybe I'm a male lesbian!

My theory about human sexuality has always been that it exists along a spectrum (at least in the subconscious); there just ain't many true black/white situations in reality.
I won't give you advice about what to do sinnce you're married, but I think your therapist is the one you should hash things out with...Get some clarity in you head. Good luck, & don't let it trouble you any more than you already have.
