General question

[bs301]

Please clear this up for me because I am a bit confused. I know that the HIV virus is found in blood, seamen, saliva and vaginal fluids but there is a lot of talk about getting into the blood so I'm mixed up.
Now lets say two guys have unprotected sex and the top man(HIV+) ejaculates in the bottom man(HIV-) Is it enough that he ejaculated in him or would there have to be some sort of tearing in the bottom mans anal cannal that results in some sort of bleeding for the virus to get into?
Same question but with a male and female senerio. Would the female have to have blood present in her vaginal secretions to transmit the virus to a male or is her vaginal fluid alone enough to pass the virus?

Teak, are there immune rich cells in the mucosal lining of the mouth?

[Teak]

Mucosal tissue lining in the vagina and cervix can chafe easily and are rich in immune system cells that can be infected by HIV.

So if I understand you correctly its not necessarily the fluids that have the virus but blood that may be present as a result from anal or vaginal tearing? Or in the case of saliva from bleeding gums?

[Teak]

That that is false to say there are not tears when having anal and vaginal sex. It does cause small tears in the lining of both.

No, there wouldn't have to be tears.  The lining of the vagina and anus is comprised of mucous membranes, which are very vascular.  The virus can be transmitted via the  mucous membranes .

There are always tears when having anal or vaginal sex.
