Would ulcers/canker sores be an effective passage of infection? If possible I'd prefer someone to give me an proper answer rather than 'oral sex poses no risk'. I have read that because ulcers/canker sores are effectively 'open', it is easy for things to pass through to the blood stream. Some sites say there could be microscopic cuts inside the actual ulcer. Any opinions?
Surely, if it's a break in the mucuous membrane (which I think an ulcer is), any HIV-infected fluid can be absorbed easily? If it can pass through small cuts or rips in the vagina/anus, why not the mouth?
How much fluid would need to enter the ulcer for HIV to be transmitted? I know you say there's no risk for oral sex, but I really can't see how canker sores/ulcers wouldn't be a risk. PLEASE SOMEBODY CLARIFY WHY THEY AREN'T A RISK! PLEASE!
Please, I need answers. If I can get a straight answer on this I can stop worrying! For good!
