Its best to go to you Gynaecology department or doctor and have it checked out, as they will be able to give you a clearer diagnosis. If you have symptoms as you say then they will be able to identify what they are.
I have experienced something like that but it got worse, it went from my legs and thighs directly to my balls, and it hurt severly, i thought it was jock itch but no. The pain was immense, i went to the hospital, they gave me a pain killers and a antibiotic, then as the days passed, the bumps dried and flacked away,
Also how can i test for this std hpv of genital warts or how can i know if i have it. I talked to my doctor and she said there's not a single way to know if a guy has the hpv virus unless his partner girlfriend or wife has it
