Is Slight Tingly Sensation In Vagina With History Of Having Unprotected Sex Indicate STD?

hi there,

last tuesday i had unprotected sex with a friend. I noticed nothing unusual about his skin or penis, and he has never mentioned anything to me. I dont know if it is just because i am vey paranoid about stds, but recently ahve been having slight tingly sensation in my vagina, and i cant tell if this is something i should be worried about or whether i am just making these sensations more noticeable than they really are? please help
