Itching! What is it?! Please help me.

A year ago I was checked for STD's and came up negative. I had the same partner since then and she has too (I hope).  Now I have constant itching on the shaft of my penis, on my scrotum, and near the rectum area.  I am also experiencing small pains in the left abdominal area sometimes and groin. I don't know if this is related to my work outs because I work out vigorously and sweat hard every day and fail to take a shower right after. That leaves my genital areas soaked in sweat and dirty. Could all of these be because of how much I worked out? And being careless of my hygiene? Or is it because of the sex I have with my partner.  Now I have ONE painless, tiny not noticeable skin colored bump above the mid part of my penis.  Under my penis.  What could this be? I researched a lot about herpes because that is what I'm scared of.  It has been 18 days since I performed anal sex for the first time on my girlfriend but again, we're both clean. The bump showed up not too long ago, but I have yet to get other symptoms like fevers or swollen lymph nodes.  Just the ones I listed, but again I don't know if those are exercise related. Please someone help me! Thank you.

Thank you for your reply.

So the bump on my skin could be because of fungi??? And the pains I've been experiencing isn't STD related? Ill be checking in with a doctor soon.  I have checked this morning again, it still remains at one bump only.

Sounds more fungial then anything. See a Dr to verify this.

by the way, the bump blends in with the folds of my penis. that's how small it is. Im really confused about it.
