Is there something wrong with me?

1. So I use my dildo to see what I like before me and my SO have sex. I already know I need to stimulate my clit on order to climax but I've noticed w my dildo that even if I play w my clit I can't moan.

2. Whenever I'm not with my SO I want to have sex w him, my sex drive is high, I had bizarre fantasies but they aren't that bad. When I'm with my SO it's like my sex drive plummets. Does that mean anything or am I just overthinking everything?
