What Is The Small Bump In My Penis That Has A Slight Discharge?

I have been working out a lot lately. Running and sweating daily. I am a 33 year old male by the way. I notice I get small very small white heads that pop.. Like clogged pours. But if I wash a lot and keep dry, I don't get them. So out of no where. I noticed lump at the bottom of my penis shaft. Not huge but noticeable. It looks inflamed and red after I shower. Other than that, I kinda blends but is still there. The skin looked kinda odd.. Like dry or flat, ingrown hair, or inflamed or infected pour. But I squeezed it a little and it was sore and white chalky/ clear puss came out. It's still kinda there. Never had this before. I out some ACORTIN A on it. It seems to be helping.
