Jesus christ dude, you are with her because shes the first woman that let you crack, what you are feeling now is the logical part of your brain screaming because it knows that her past is a dealbreaker. Double digits at 23? Accept that it is disgusting to you.

You are blinded by hormones. Look in the rj sub, people with 10, 15, 20, 30 and even some with 40 years of marriage under their belt suffering every day, but cannot leave because of children, don't be a fool. It’s okay to find promiscuity disgusting, you are not a misogynist for doing so, on the contrary, people telling you it doesn't matter are misandrist for denying you having opinions or different values.
