Riding help

I’m insecure about my body, and I feel like that holds me back but I don’t know when I’m on top I don’t feel much pleasure ( sometime I do) so I don’t know if I’m doing it right or if I’m just to busy feeling insecure about my body that I’m not trying..

Helppp how do you ride?? What easier ?? Knees? Being on your feet/tippy toes? Tippps please.
