The OP seems happy that the rash has gone but as he admits to having exposed himself to risk he cannot be certain he has not contracted an STD without undergoing a complete STD screen.

A screen need not be expensive and only involves a blood test.

The down side is if he does have an STD and does not get it treated he could pass it on to girls, who could then pass it on to other boys.

We could be looking at a new pandemic with OP as Patient-Zero.

Whilst you may be joking your post contains much truth.

It is not Herpes. They will not produce 50-100 sores.

Dude, it was a rash maybe from food, soap. Are you taking any medications? Who knows. I have gotten them twice before.

I would not waste your time and money on STD tests. But, up to you.
