I remember it happening once or twice.
Once we were in a hotel room (The Man and me) and we had been having sex for hours. I was using spermicide foam, but had bought these spermicidal suppositories I wanted to try. I thought they would be less messy. I was already a little sore, but I tried it. OMG! It burned so badly, I was doubled over on the bed crying. My Man took me into the tiny bathroom and we tried to get the suppository out in the shower. It hurt for days.
I mentioned it to a friend of mine and before I could tell her what happened she said, "Oh yeah? Hot tamales, huh?" She had had the same experience with these spermicide suppositories. Never again.
I started to get really sore after a few months on the pill. I was told by my GYN to "use lube." I was too cool to buy KY, (I was 16 or 17, gimme a break) so I.... went to Spencer's and bought this horrible flavored tube of what was most likely pure glycerine (I think it was either Motion Lotion or Joy Jelly) and it made the problem worse. I really didn't find a decent lube until we started shopping at sex toy sites.
