the best thing to do is to be seen and get a proper exam done. sometimes you can have fragile skin in the genital area that needs extra tlc too. sometimes it's a simple as a barrier cream applied regularly to protect the skin ( like aquaphor, desitin, a&d etc ) and other times you benefit best by using topical estrogen cream to strengthen the skin.
could these be herpes? well they could be. that's why a full work up is in order. odds are that you've never been tested for herpes before to know your status. also sometimes chronic yeast infections cause these issues too.
