Cowgirl position, need tips!

I have ALWAYS been so self conscious.. not really about my body but just how to move right.. when I move my hips back and forth I can hear this weird noise as if my stomach or some organ inside me is moving with his dick and it’s awkward 😩☹️😞can someone give me some tips?

A man has never made me orgasm.But I think the reason for this is because I have been masturbating for so long to a shower head, that only that can get me off now

Also just any other sex tips in general?? Someone told me to play with his balls while in doggy style, and my guy really loves that. Anyone got anything else?!
