Your rash has none of the characteristics of herpes. The distribution (groin and perianal) suggests irritation or psoriasis rather than yeast or fungus. In my experience, once you get rid of the inflammation (in your case with one or both of the costisones--betamethosone and desonide--rather than the antifungals--clotrimazole and Loprox, the best thing to do is stop everything and just use a bland moisturizer, if that.
I don't know what to make of the Western blot test, and cannot undertsand why it was done. I don't think the canker sores are related to anything, nor is the irritation at the corners of the mouth relevant.
Time to stop worrying.
Just to add: Base of my penis is still itchy. There are no blisters of any kind and have not been. Do you think I should get an STD test? Could this be diabetes? My Dad acquired that in his early fifties and I am in my late 40s.
One more thing... I have had itchyness in my eyes and ears and some bumps, small pimples on thighs which almost looks like tiny red dots that appear like a bite, they are two right next to each other...very small (no vampires around). Hehe, talk about being focused on my body! Anyhow, thanking you in advance for your help. I have never had any think like this before. I think my nerves are making break out all over!
Rashes in the crevisis of your groin are most certainly jock itch. I wouldn't worry to much about it. You haven't had any blisters and itching is common in that area.
