10% of the world sexually active population has HSV2. I can imagine it's not pleasant, but it's nothing really serious.

How do you know you have HPV? It's believed that over 90% of sexually active males have it, so once again not that big of a deal.

I think the main issues you have is the shame of what you did l, as well as the guilt of it. Cheating that is.

The real fuckup was cheating, not getting those STDs.

(Also 400USD/h is not at all cheap, and it sounds very suspicious that you contracted all that within few seconds of unprotected sex. There might be more to the story)
