A young woman who is married but is a sex worker and I began having sex and after we got to know each other a bit she allowed us to have sex without a condom. We both loved it. She let me cum inside of her and afterward she wanted to cuddle. However, the next time we spoke she told me she had pain afterward and was sick. She explained that when a woman's body gets used to a man and then she sleeps with another man it makes her sick and is painful because her body was used to the one man's chemistry. I asked a few other young women and they all confirmed that that's the case. So, my question here is if there's anything that can be done to mitigate that, or if it would go away in time if she continued having unprotected sex with both of us.
