When my wife was younger (18-23) she used to complain that I was hurting her sometimes, too. As she got older, and probably more relaxed about sex...she never complained about any position...it was more mental than physical, I believe. It wasn't as though she wasn't into the act, but it wasn't until she got a little older that she really loosened up, so to speak.
Since we've also had a couple of kids now I guess anything I have to offer isn't in danger of expanding the space more than it has already been expanded, too.
Sorry that my solutions may be to wait for a few years or make her have some kids...not great options for a younger guy, I realize...
