Thank you my good man. I got another opinion from a mate who said it was only a threat if there were sores on my anus. But I'm almost certain there weren't, otherwise I'd worry about blood.
Not a risk. HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
Mother to child
