I had unprotected sex with a guy on the 4th of july.. i just noticed a sore on my vagina that looked like a gelish scab yesterday. it washed off in the shower and scabbed over, since then i have noticed an open sore on the frenulum of labium and one more on my labium majus they are painful but it does not burn when i pee, i do not have any head aches or muscle aches, i feel tired only because i work out twice a day. i also started my period yesterday. i felt like i was having a yeast infection about a week ago then the symtoms started to go away. now i just have a total of what looks like 4 open sores. i am worried that it is herpes but from what i read the symptoms were i dont have any of them. no fever or flu like symptoms either, however they are just open sores that hurt, only when i shower and washed with anti bacterial soap it burned, is there any reason why i should be worried? the sores are not close together like a cluster either.
