Can’t orgasm anymore help!!!!

So, my husband and I have sex like almost everyday. I love for him to be on top I think it’s more intimate but anyways most of the time he is on top. Almost every time I would orgasm, but recently well this has been happening for a while but, I can’t orgasm anymore at all when he’s on top. Sometimes when I’m about to orgasm he cums then his dick goes down.. it’s been really frustrating.. Is there something we can do or another method?? In the past he would go pretty fast for me to orgasm seemed like the only way but now he tries to go fast but then he cums... In order for me to orgasm I have to ride him now.. We been trying different positions but it doesn’t seem to work.. Please any suggestions??!
