Everything is really based off of speculation and estimate.
I was also wondering about the fact that it is said that 5% of HIV infections are transmitted via oral sex. Does this happen in extreme cases, like when there is a lot of blood involved or when you get semen in your mouth, or are these figures based on nothing?
Ok thanks.
Just for reassurance (or not?). If his chapped upper lip was bleeding a bit without me noticing it, would there be a risk then?
