Living a weird sex life

I genuinely feel like I have no sex drive. My partner never really minds but I truly feel bad because I used to want it all the time an after I got on my birth control it’s like it just disappeared. And it started to get semi painful. (Not disease related I just got tested at the gyno) she tells me it can be normal so I’m wondering if anyone has any advice on to refresh my sex life and make it a little less painful. It feels almost like a rub burn type feeling.
