Possibly NSFW: Do you think it's appropriate to talk about dating and relationships with a therapist?

I have a feeling most people think it’s absolutely okay to do so, but I still feel a little weird about.

I’m a guy and bisexual and I had my first date with a man last week and we were physical – and it was beyond awkward. I have a fear of being in a committed relationship and being vulnerable, as well as sexual intimacy, so I really want to bring this up to my therapist. I want to explain to her how I felt while having sex and the fears I was having, but I’m afraid I will be revealing too much info or come across as creepy.

What are your thoughts?
