Red Rash on Head of Penis

Okay, so about a year ago I was masterbating (masturbating) and after i finished, it seemed as if i had some sort of a frictional rash on the tip of my penis, which in turn was extremely sensitive and was also painful during showers from body wash etc. This rash went away after a week or so and i didnt have anything relating to it until recently when the same sort of thing occurred but only in a minor form. The only difference is that this time i feel like the rash is causing the tip of my penis to be even more sensitive than usual. About a week after it happening i was having sex and with a condom on i only lasted around 2-3 minutes, when previous to this incident i could last much longer, around 30-45 minutes without cumming. Even now with masterbating (masturbating) my penis becomes extremely sensitive and i cum within a minute or so, which is concerning me and shunning my confidence. The rash itself just looks like a red spot maybe the size of a nickel on the tip of my penis. When i stretch the skin apart there are tiny ridged where the rash seems to have been raised, but the rash itself is not raised from the skin at all. This most current incident occured probably around a month ago, and im still having problems lasting and what not. Im not sure what to do about it, and currently im not up for asking my parents to take me to the dermotologist. And help or suggestions?

your regular doctor is fine for this. no need for a specialist.

odds are this is a fungal infection though many other things it can be. being seen and getting a proper exam is the best thing to do.
