OK, firstly your direct question. The lesbian thing. Originally you were asking me if god should condone this and no other, and telling me how silly i was for believing this. I replied saying that i didnt believe in god, and so it didnt make a difference to me. To answer your adapted question, I dont prevent anyone from having sex, and dont see why anyone should.
Right you keep jumping between Western Europe (and countries) and worldwide, and so your figures can jump around too. Now your western europe numbers do indeed point out that it spreads more through heterosexual contact. I havent disagreed with this. What i have disagreed with is that this means that it is more likely to spread through heterosexual contact. If the numbers are 2:1, i dont think there is a 2:1 ratio between heterosexual men and homosexual men, suggesting that in proportion to numbers it spreads fast in homosexual encounters. (your previous stats were saying 44% hetero and 26% homo werent they?)
Now we jump to the world picture. Once again i agree fully that it spreads most because of heterosexuals. And the reason i suspect it is higher than this as i have said is because i know the west isnt the world, ive seen the effects in the third world, ive seen the big billboards with familys on asking the men to be loyal, so that aids doesnt spread anymore, or if there not loyal then at least wear a condom. Can you please stop insisting that you know the way i think of the world.
As far as i am aware, vaginal sex is not more damaging that anal sex. Now if a heterosexual couple engage in anal sex, then their at just as much risk.
Anal sex is where increased risk occurs. I am assuming (possibly incorrectly) that proportionatly (so trying to even things out here) male homosexual couples engage more often in anal sex than heterosexual couples.
Male semen contains a lot more particles of the virus than female vaginal fluid, this could also just as easily explain the trends.
Can i just say once more Anal sex is more risky (as far as i am aware), and so that is where the health risk can lie. And i believe that i have already answered your direct question.
