Hi I Noticed The Day After Having A Lot Of

Hi

I noticed the day after having a lot of sex , a small bump on the right side of my penis shaft .
I'm circumcised and it's right on the rough skin part that I read is where your skin is retracted from circumcision.

There was no lube involved with the sex and it looks like a irritation bubble from too much rubbing

It's been 2 weeks now since I noticed it and there has been no change in size

I've seen many times irritated skin after sex (girls claiming the size is too big and there too tight causing marks on my penis afterwords ) but it usually heals quickly

I've had no itch , nor pain and it doesn't look like herp or a wart ..

Not sure how to post a picture
