About two weeks ago I got blowjob from my girlfriend and accidentally her teeth leaves a cut on my penis lower head and I immediately feel the pain of cut and found some blood stains there I washed it off that time I didn't think of it much and gave me blowjob again next morning too after that it almost took one week to get that cut cured. But now I'm tensed should I be worried for any kind of infections? Kindly help please.
