The last two times I met my ex boyfriend in a public space, he wanted me to penetrate him (I don't like penetrative sex) since I never did so when we were boyfriends. All of this in a public restroom by the way, and those two times I was really uncomfortable and had to tell him to stop and would just leave the restroom while he was masturbating inside, I did seethe internally since having sex in a public restroom is very disgusting. What should I do now? He doesn't know I don't like that and he wants to keep going out with me even though he isn't my boyfriend at all anymore
