I can understand that it would be very uncomfortable to bring this up, but there is so much to gain from this. You're not disgusting or bizarre and honestly it's very very common. I have had erotic feelings for my therapist whilst I see him as a father figure which was very confusing. For me it was easier to admit all of this in email instead of in session but it got us talking. He didn't shame me for having these feelings and any therapist would handle this with sensitivity because they know it's hard to talk about.
