You cleaned the hair as in just washed it, or did you shave at all? If you shaved it could just be ingrown hairs making small "pimples" appear. If it's just a wash and then since having sex with your lady they appeared it could warrant a visit to your doctor... Especially if it's causing severe pain, I would go either way, just to be safe!

You have herpes

Or an ingrown hair...

I drum it by machine I didn't shave it .there is no pain but just if I touch the area in my finger I will feel the small spot like burning ,
