Dude, that's not a problem at all. Go to the hot chicks that will make you forget about such trifles. Girls often do not understand that we need sex anytime, anywhere. But if it did not work out with one, then the man will go to the one with which he will succeed - this is instinct and no more. Therefore, let her be offended by you - but this is not a reason to refuse her needs.
Many girls do not understand that we need sex, as well as food, air and water, thereby moving us to what we cheated on them. Well, what to do, they themselves decided so. In such cases, I just do not hesitate to go to my escort and order something light, like an erotic massage, blowjob or easy domination. It helps me to relax and forget about all the differences.
