I had sex with my boyfriend for the first time today (I’ve had sex before, just not with this guy). He wore a condom. When he pulled out, the condom kinda slipped off his dick and stayed in my vagina, and I had to pull it out. Then the cum got all over the place, and it was sort of around my vagina as well. I couldn’t tell if any went inside (cause I had to pull the condom out), so we tested the condom by putting water in it to see if it would leak (it didn’t, it was fine). And then we wiped everything down. I’m still very nervous that some semen might have gotten up my vagina since it stayed there and then kinda spilled everywhere. Should I take plan B in the morning? I’m leaning towards yes, but comments would help.
