why is the sex getting worse??

steph
Me and my boyfriend used to have sex almost every day more than once and it felt amazing I would cum over and over!! 
but now it really only feels nice when I rub my clit?? when I don't it's not as good?
And when I run my clit I have a huge orgasm then it goes really sensitive and the sex is NOT enjoyable at all😔 any advice? what can I do to change this? cause we always try new positions but is doesn't feel good as much😕xx
