This is embarrassing I've ask some women but wanna know what you prefer. When a woman is riding you do you prefer bouning or grinding how does each feel different to you?

I ask because i have a disability & my lower half find it difficult to bounce so i can only grind. Also i don't always have lower sensation when he goes down on me & when he enters me sometimes i think is he even in. I've asked woman what i should do or how my man can help me feel but i still don't have an awnser. So wondering if this has happened with you in a relationship woman have lower half weakness unable to bounce & loss of sensation vaginal wise was there anything you done to help
