Ok, the title is a bit dramatic haha. So last night me and my girlfriend had sex. I used a condom, but when I finished and took it out I realized it had rolled up a bit about halfway (still covering the top completely and what not). My penis was moist when I took it off, but I am unsure if that was cum, the lube from the condom, or from her vagina. I took the condom off after sex, but I am worried it could have gotten inside her somehow? I am not really sure. It basically just was not on all the way I guess for whatever reason. Should she take a morning after pill? (I know they work for 4 days)
