Irration scab on Penis

Wow, this is really embrassing, but anyways.

Lately I've been dry masturbating alot (around 3x a day?). And over the last two days I've had a scab develop on my foreskin. I dont think it is an STD because I've always used protection, however I do not wish to completely rule that out. I feel this may utimately just be a irration scab that has formed. It is a tiny scab, about 1mm big and does not hurt, itch, bleed or puss, however it is alittle red.
Any ideas?

Thanks!!

Sounds like too much friction, try not masturbating for a while.

If not it may be some sort of dry skin, check in with your family doctor to make sure.
