It probably is more to do with the style of sex which is more likely to transmit given the more physical nature of it. Small cuts and tears and whatnot. Don't really want to go into more detail then that.<quoted text>The question is Why are Gay men according to the government the top spreader of the HIV virus? why is that? you still not answering. Is is because Gay men are more irresponsible in their sexual lifestyle?
Vaginal and anal sex are the most common ways to transmit also meaning that straight women and gay men are going to be the ones getting the disease more often being on the recipient end. Not that both parties aren't at risk but one is more so then the other.
My guess is men in general are less likely to get physicals or to more responsible when it comes to protection.
I was going to Google some things and decided its more than I feel like getting into right now, especially since i have stuff to do, so if someone has info to disprove it they are welcome to share it. But that would be my guess anyway
