IM WAY TO WET

Sex is awful. I used to get off every single time before I had my son  and now I barely feel him, he constantly slides out, and it's hard for both of us to get off. I constantly tell him to just stop cause I'm too wet and he says no I'm not which i know it's just to make me feel better but I want my sex life back and can't even enjoy actually dread it and feel really self conscious about it. How am I supposed to keep him only wanting me if I can't even please him in bed 😩
