Re: Could This Also Be Herpes?
It could be herpes, but one thing I would say is that since I have had genital herpes (HSV1), the whole genital area has been quite a bit more sensitive. The skin is dryer there and I get a lot of irritation from using scented bubble baths etc, which never used to happen before the genital H.
So this could be related to the herpes, but it might just be irritation - a "diaper rash" appearance suggests irritation rather than herpes to me. You could try changing your underwear, detergent etc and seeing if it makes any difference.
