First off, plenty of people have or do feel the way you do. Secondly, this might help answer the question: Do you imagine yourself living with a woman for the rest of your life. If you answer yes to that question you more than likely not you're a lesbian or bisexual. I hope this helps at least a little bit. Oh, and before I forget, have you told your therapist that you need to talk about this? If they aren't or don't seem comfortable maybe you need to think about seeing another therapist.
