If I masturbate a man, assuming he is HIV positive, and his semen comes in contact with my body, is there a risk?
2: If I rub my penis ,the glans, against his and our precum or cum come in contact, is there a risk?
3: If I suck a sexworker's breasts and lick her sweat, and have a sore or an open wound in my mouth,is there a risk?
4:If a sex worker does a blow job on me,or I on him/her, is there a risk?
Thanks a lot.
