I visit a massage parlour a 7 days ago, after the massage the girl told me that she was on her period as i also saw some blood in her underwear, she was naked and she touched her vagina, i am not sure if she inserted her fingered in, after that she used the same hand to masturbate me but before that i put some massage oil in her hand because i was afraid that her hand will have some blood and hope that the oil will kill all the virus or bacteria, my question is will i acquire std from such activity? And now i feel itchy at my penis and sometime hot sensation but not all the time, i mean it feel better sometime, i do not have any stain in my underwear or any discharge from my penis, i also have a mild sore throat now, could this be a std infection? Do i need to get tested, please advise, thanks.
