Urology/Bad penis rash(?) under shaft


I noticed a few days ago that I had quite a nasty rash on the underside of my penis shaft; it's, red, looks raw (like I've taken the skin off), and is itchy. I'm not sure if it's something like a fungal infection or a result of some rough sex when I was drunk with my GF. Any who, it is yet to heal (i stupidly have had sex a few times since, both painful and obviously only further worsen it... safe to say I won't anymore) and looks and is slightly painful and itchy. I highly doubt it's an STD because of my long standing relationship, I'm assuming it's either a result of the friction or possibly a fungal infection? I assumed the worse with the latter so have been using Lamisil cream 2-3 times a day for two days so far.

Would it be important to get an image? Thanks a lot.


Remember that we are not allowed to give individual diagnoses on this forum so sending me a picture won't help.  A fungal infection is most likely, but obviously we can't be sure without actually looking at it.  If the lamisil doesn't work, talk to your local physician or consult a dermatologist.
