Sex always hurts 😥

I’ve been with my boyfriend for over 4 years and every time we have sex it is really painful at first. He is pretty big down there and I guess I’m really tight, because it feels like the first time every time! Even with lube it doesn’t really help that much. Idk what to do 😭 sex isn’t that pleasurable for me, it’s mostly uncomfortable and trying to ignore the pain. Side note the birth control I took for pretty much the whole relationship (lo loestrin fe) made me crazy I think. I was never in the mood and I was always so emotional and anxious and depressed. I’m off the BC now so I’m hoping that improves our sex life
