Partner has herpes. i've been having itch, tingle, and enlarged groin nodes always around the time of my period but nothing visible. do i have it?

Not herpes: See yesterday's reply. Also, herpes outbreaks never last more than a few days; recur no more often than every 4-6 weeks; and between outbreaks there are no symptoms at all -- no tingle, no itch, nothing. If you have more or less continuous or more frequent symptoms, herpes cannot be the cause. Even pos blood test wouldn't help: it would mean asymptomatic herpes plus somother cause of the symtoms.
