How long does PP pain last with intercourse?

Baby is already 3 months, but anytime my husband goes a little fast or too deep to quick, I have vaginal pains. This isn’t my first baby, but I can’t seem to remember what my last experiences were. The pain is only during intercourse, I had no tear or stitches or anything, so idk what’s going on. I guess I’m still healing or something, but I thought it would have been gone by now. Sometimes even with a slow start, it hurts a bit. Nothing crazy, but enough to put a damper on the fire, so to speak.
