Hello, I have been with my girlfriend for a few months now this is the second time that we have dated and I feel like this time is really serious. I want us to stay strong and I know people have wants and desires and quite frankly I get off from the thought of my girlfriend getting pounded and filled up by someone else in front of me. I brought this to our attention and she is not for it. I don’t understand why, I need help on getting her to change her mind.
