i had sex with someone, i made him anilingus for 1-2 minutes and the only ocassion before the penetration. later i penetrated him. in the middle of this i take out my penis and see a little blood of him, but we were so horny that we follow. i want to know is there some risk; cuz i had a little lesion in my mouth ( inside in my mouth and under my lip). i never made him oral sex. also i had an injury in my left hand for the gym , but it was dry and i never used this hand in the act. im a little worried and thanks guys for your time.
