No pleasure

Alright so, I've been having sex with my boyfriend for a while, and for some reason I never feel anything, like I can kinda feel he's inside me but I don't feel anything else, I'd moan & I get wet but I just don't feel pleasure, even when he fingers me, I don't feel pleasure on my clit, it just gets red & it itches. Even with my ex I never felt pleasure & out of all the times he fingered me only one felt good. Can somebody help me figure out what's wrong with me?
