Another FTM here. I was super dysphoric about having a front hole and definitely didn't use it in play. I had vaginitis until I started T so I couldn't even use tampons. We're talking extreme pain here. After T my dysphoria lessened and I've used a toy in there and it felt pretty damn good although I end up feeling crappy about myself after masturbating when I use the front hole. Probably I am still somewhat dysphoric. I always thought I shouldn't have a cavity there and I should have a penis to pee. I don't have a phantom penis, though, so my bottom dysphoria is not as severe as some.
