I'm 22 year old male from India. I have masturbated inside dirtiest public toilet SEVERAL TIMES . My concern is that, if I have touched the HIV positive bodily fluids on toilet seat or door knob unknowingly and use the same dirty hand to masturbate and used the same hand to clean up the semen from tip of my penis. Just by this situation, is there any chance of contracting HIV from above scenario.
No sexual intercourse and no intravenous drugs usage till date.
