Transcending Sexual Phantasies

I was encouraged with my therapists to talk about explicitly and any sexual fantasies that i had. They would question me about, you knowi if i found a certain at school attractive. But it went a little deeper than that. The actual fantasies and stuff that i was experiencing as abnormal 16 old kid would be mnd trying to morph those fantasies into a heterosexual type way. That's like a more active sexual role than a passive. I don't know, is there ther way to say that? I think thats i don't want, iis super explic i don't wants to be either.
