When I had sex it was for two seconds, they just put it in, and my partner didn't even ejaculate afterwards, there was a condom used, and it was JUST after my period ended.
It was a month ago when this occurred. A couple of days ago while masturbating I felt a hard and round but soft ball towards the left of my vagina. I got very nervous by this and today my vaginal walls just feel a bit swollen. Please help as soon as possible, thank you. I'm very nervous and frightened.
