I sympathize with both guys and girls in this thread. I had skin tags too, unsightly bloody things but managed to get them "shaved" - painless and quite a relief.
I also had scrotal cysts, little white spots on my testicles, totally benign but again, unsightly. When a girl refused to to anything when she saw them, I knew it was time to get them removed. Once I'd got over the needless embarrassment of seeing the quack, he referred me to a urologist and they were removed too.
The point I'm trying to make is that apparent blemishes like these may look awful, could be benign but, of course, could be an indication of something worse. If I saw a lady with something similar, I would urge her to get it checked, for her and everyone else's benefit. I'd probably make up a story that my sis had the same thing and it was quick and painless to rectify, that way she would be more likely to see the doc!
