Can I do what I want now?

Me and my girlfriend broke up about a month ago. This break-up was not because of us not loving each other anymore, it was because there is no chance for us to continue with the relationship - it is a secret from her family and we have great religious and cultural differences which are too great to ignore in the event of going any further than this. We still meet up quite often and we kiss, hold hands, tell the other how much we love each other and we always bring small gifts when we are going to meet up. It is hard to see how anything has changed since we broke up. Now, tonight, there is a booty-call girl waiting for me to give her the word regarding casual sex. I was dating my GF for 16,5 months and we haven't had sex once due to her vaginal problems (she has excruciating pain during sex, she has a fungal infection which has been hard to cure). I have not cheated on her, I have controlled myself the entire relationship and tried to wait for her to solve the issues with her genitals, yet to no avail. I know that we have broken up but I am afraid of hurting her feelings if I would have casual sex and there is no way in hell she would ever even know. What should I do? Can I look her in the eyes without being ashamed, feeling like a textbook A-hole for doing this?

hey i understand that your having problems and its understandable that you feel like that when your having sex with someone else but its also true that everyone have needs and since your not together anymore i dont think you should feel guilty about but if you ever do get back together and you feel guilty about having sex with someone else i would suggest that you tell her before you are offically back together or your going to feel worse. sorry if im not very helpful.
