During this past summer I've been working alot and sweating alot. And I've been getting these large pimples that would last for sometimes up to 2 weeks around my pubic area. They also hurt alot, sometimes everytime I take a step I feel it throbbing. I'm a bit worried it could be something else than pimples because how big they are, like herpes. But I've only had relations with one woman who was tested after we broke up and she's clean.

I'm also a large guy. 6'4" 330lbs. Possibly thinking it's just large sweat pimples but I'm looking for a second opinion.
