I Can't Feel Anything During Sex, I Can Feel Him

I can't feel anything during sex, I can feel him going in and out, but that's about it. I can't orgasm that way.. I've also stopped inserting my fingers into my vagina while masturbating because it's the same; nothing. The only way I can orgasm and feel pleasure is if I play with my clit, and only my clit. I have NEVER orgasmed while a man was on top, I usually do when I'm on top because that way I can focus on my clit. But with my boyfriend, that doesn't work either; he cums too fast and he's always so quick to get started and to finish, there's no more foreplay in our sex lives anymore, either.... My "condition?" Doesn't seem to be normal... I just want to enjoy sex like normal people.... And I want to know what's wrong and what I can do to fix this..
