Rash on penis, possible STD need help

Hey people, so I've had this rash on my penis for the last 2 months. It doesn't seem to be spreading or getting better. It does itch occasionally and I haven't had any blisters or sores. It does seem to get more irritated when erect or masturbating and it's not responding to and anti fungal creams or otc steroid creams. Does anyone have any idea what this could be? I just want to get some ideas while I wait to get tested.

the tip also does seem irritated. doesn’t hurt to be but does feel a bit warmer and does tingle a bit.

seems like it is irritated. Keep it dry.

Don’t use soap for a few weeks and apply coconut oil

Avoid heavy sugar intake and drink more water.
