Red Panda brought up a point I had missed entirely. Thank you.
I still maintain that a degree of sexual preoccupation is to be expected...particularly at 20. But, your views on your own body do speak to something I had not considered. Viewing yourself in an only sexual manner is, with all due respect, problematic, and if that's the angle your T was coming from, I do certainly see her perspective more clearly.
The bright side though is that your therapist is here to help you with that.

Her goal is to get you to see the value in those things, and, as is necessary, to break the notion that sex and sexual activity is the only fun there is. Certainly to break viewpoint of only being able to look at yourself sexually. There's SO much more than that to you...your therapist is only trying to help you see that.
I do apologize if it seems like I'm pulling a total about face from my last post. I do still maintain that the sexual humor probably isn't too out of line in and of itself. But with your recent posts, I do see where she's coming from, and I think she may have a valid point...it's not the humor or the thoughts in and of themselves but the methodology of your thinking that prompts them, if that makes any sense. Nothing that is insurmountable by any means.

Just perhaps something to be aware of, is all.
Hugs,
