I think you can address whatever you like Squiggle, and I don't think it's dumb at all.
I discussed the same topic with my T over a couple of sessions.
While it wasn't causing me any trouble in my life, I just needed to admit it to someone like her who is a mother-figure to me, and have her tell me I am normal. It was then that I realized how much shame I felt around my own sexual feelings, and getting to have the "sex talk" with my T helped me tremendously. I feel like I got to experience something that was vital to my development that I missed out on earlier in life.
T's positive views have definitely rubbed off on me, and as a result I no longer feel embarrassment to bring up such things
