My Orgasm Changed... Please Help!!!

Okay so I used to be able to orgasm during sex often. Most of the time it was from me riding him on top and him touching my clit. But we had some time apart and I started to make myself come in other ways like with my hands and with the shower head. Now I can’t come during sex anymore. Like it is impossible. The only way I can is when he goes down on me. I feel like my body has changed the way it orgasms! Please help me.
