Red dot on my foreskin

I do believe it is the second time I've noticed it. The first time, after I've masturbated I noticed a few small red dots on the outside of my foreskin, and one that was a little bigger than the others. It does not bother me, I cannot feel anything, not even if I feel with my fingers.
There was almost a month until next time, which is the day I wrote this. One of the dots came back. Still, I cannot feel anything when I touch or anything. The only way I discovered it was whilst I was at the toilet. I masturbated the day before that, too.
By the looks of it, the dot(s) appear when I masturbate, and when it gets a little rough. The first time they appeared, when I masturbated it was a little rough. The second time I pulled the foreskin a little, and it might have been rough for the skin. It takes about 1-3 days before it is fully gone. I've never had sex, so it is not an STD. I do have some cream against eczema at home, if needed. Of course, I hope that it is only because the skin have been under stress.
There is nothing else to see. There is not a dot on the same place, but in the inside of the foreskin. There is not any dots on the glans or anywhere else, either.

Doesn't look like worrisome to me. Could be due to rough masturbation, try to apply lubs before u do. Even Johnson's baby oil will do...
