Of course being there brings the feelings up! That is to be expected, and hopefully, your therapist can reinforce the normalcy of what you're feeling, regardless of your gender or hers. I'm gay, have known and been completely okay with it since I was 16 years old (and I'm in my late 40's now), and my current emotional experience with my T is way beyond my experience or understanding. Those projected feelings and attachments are intense and confusing enough, without throwing questions about your sexuality in the mix. I can't imagine working through all that while worrying about sin and shame and rejection of your essential self.

boredporcupine is right: you may not be able to resolve this in an environment where something as essential and deep as your sexual identity is condemned or rejected. It's shaming and can be very damaging, and it's not going to go away. Rather, it's likely to get significantly worse, and if you can't speak openly about it to your therapist without fear of condemnation, therapy isn't going to be of much help at all.

So, two questions: Is it absolutely necessary for you to seek Christian counseling as opposed to a more "traditional" therapeutic model? And if it is, are you prepared to openly speak of your questions about your sexual orientation with your therapist, and accept her recommendations or treatment?

If not, you owe it to yourself to seek help that doesn't come pre-loaded with judgement. My experiences (and, granted, my biases) tell me that conservative Christianity and the healthy exploration of sexual identity are incompatible. Your experience may prove different, but unless you face that head-on, it's likely to keep jumping up and biting you.
