hello misswhiskey id have to say your best to go to the doctor and have yourself looked at . its really nothing to be ashamed of and its most likely herpies wich any1 can get from just sitting on a toilet set . if its really itchy and blister like its probley a siple dose of herpies so thats really no big deal the doctor can give u a cream and a few tablets to take care of the problem . so get your self checked out and feel better its no biggie luv . hope all works out for you . oh yeah dont forget to have a great day
