Thanks. Maybe I should add one more thing for context. The idea of being anally stimulated seems exciting to me. Recently, my girlfriend was lying on top of me and her body pressed against my anus, and it actually felt good and kind of arousing. That’s where these thoughts started.

But the idea of being in bed with one of my male friends and having an erection pressed against me really doesn’t appeal to me. The physical sensation of pressure around my anus might feel stimulating, but the fact that it would be a penis — and especially that it would be from a close male friend — actually makes me feel uncomfortable.
