Can I be causing damage?

[Sledgehamma]

First off I am a man who is 7 1/2 long and 7 inches around. My girlfriend has had her uterus and all removed and is only 5 1/2 or so deep. And she is a very petite woman who feels pain every time we have sex. She enjoys the pain but I worry as she has been growing to accomidate me since we have been together but it still causes her pain. And she urges me to go as deep as I can even though I know its shorter than I am. Should I be worried about this pain?

And if I do it hard and deep like she wants then she starts swelling and that makes it even harder to get in but still she wants me to push hard and fast... is that going to cause her problems as well?

You can tell her that your concerned about hurting her, and she probably will get what you mean.

They swelling is just her vaginal wall contracting because she is having an orgasm so that's completely normal.

Should balloon and get deeper the more aroused she becomes.
