Me and boyfriend were really drunk the other night and he wanted to have sex. I'm off my birth control for medical reasons right now so I said no, We ended up doing oral and he put a condom on because he wanted to have sex. I said we couldn't have sex but we could grind. We started grinding and he put his penis in my vagina but did not penetrate me. This only lasted a few seconds because honestly it was awkward so he didn't ejaculate. As I'm writing this I realize how ridiculous this sounds because he was wearing a condom, he didn't penetrate me and he didn't ejaculate but I have been peeing more frequently since it happened and I'm just paranoid I could be pregnant somehow. What are the chances I could be pregnant?
