I have a similar situation as that. I say if you can then try do a HPV test, but I am not sure if many places do it. Did you get back into contact with the girl to see if she has anything?
What you may have is an accumulative effect of different thing adding together to cause the irritation and unless you remove the exposure to the essential ones the irritation will remain, and this can be why when you have used the different medications symptoms have not reduced very much.
What you need to know is that during sex or masturbation the skin of the head and foreskin of the penis experience a great deal of friction and what this means is that things that these skin areas are regularly exposed to become a severe irritant while friction is taking place. Eventually, the mere presence of anything chemical based can become a severe irritant.
So these are things like soap, shower gel, skin creams, lotions and moisturisers, baby oil, anything that is oil based that is used as a Lube, chemicals inside condoms - eventually this intolerance can include things like soap powders used for washing clothes. The simple ‘To Do’ is to remove exposure to as many of these chemical based items as possible and the irritation can significantly reduce to the point where it no longer causes a problem for penile skin.
One simple example is, not to use soap for washing the penis - wash with water only and make sure you are completely dry afterwards.
You may have other things going on but if you remove an essential element of what is causing the irritation I may no longer exist or cause a problem …
