Bumps on my Frenulum

I have these small bumps or skin erosions on my frenulum but don't know where they came from. They don't itch, burn, or cause any discomfort aside from the fact that they're there. They also don't bleed or have pus. I know that sometimes the skin around my frenulum can tear from masturbation or sexual intercourse, and I also have a lot of scar tissue in that area. What can it be? Am I over reacting?

Your frenulum is on the underneath of your penis - this is what links the head of your penis to the top of the shaft of the underside of your penis.
What age are you?
Do you know what caused the scar tissue?
Are you circumcised?
