It sounds like she's very much into S&M, lol...she's just not told you about it.
It seems to me that you're going to have to sit her down, preferably in a neutral place (over a latte...not BR foreplay), and get this conversation going.
"Babe, I've noticed whenever we...."
"Snookums, sometimes it hurts when we...."
Then suggest a "code word" to be used as a signal that things are getting out of hand or too rough. At that point, the offending partner needs to/must stop what they're doing.
Couples usually choose a word or phrase to call out that cannot be confused or mistaken as a "time to stop" signal:
"Banana"
"Jaguar"
"George Bush" (ok, that one's a little over the top, but couldn't resist, lol).
....you get the idea.
