Condom issue?

So condoms don't really work for me. Whenever my boyfriend uses them I dry up completely and it ends up hurting terribly. Luckily for me we were both virgins when we got together, and I'm on the depo shot so we don't have to use condoms, but I'd like to know if anybody else has this issue or if anyone knows why this happens. I'm not allergic to latex, I've tried various brands, and I'm perfectly....saturated when we have condomless sex, so what's the issue here??
