The most radical tool we've got for gay sex today, positive or negative or unknown, is the Internet which I think is going to spell the death for commercial venues such as pubs and clubs because you can log in at home, go online, put in your post code or zip code, and various sites will tell you who is available in your neighborhood for sex then.  You can contact that person immediately either by email or if there is a cell phone number by cell phone or instant messaging and negotiate having sex with them and they could be at your door in half an hour and you could be having sex within half an hour of going online.  I know hundreds of gay men who don't go out any more who are were living in pubs and clubs and back rooms because they log on.  They don't have to get washed, they don't have to get dressed, they don't have to look good.  The web cam isn't switched on because they have a profile up and because everyone on that site is hungry for sex.  They're not too fussy.  As long as they know your door is open they'll turn up.  Often people that turn up don't look a bit like their profiles do, but hey, you're hot, you're desperate, who cares.  A lot of unsafe sex takes place because the web sites that allow you to put in your zip code, post code and order sex over the Internet, I mean there is no financial exchange but to just get the man into your life.  They don't ask the question about HIV except sometimes they will say some thing like "what are your views on safer sex" and you can say "every time", "not at all" or "open to negotiation" or some get out of jail card type phrase.  In most instances I know of what people have fed back to me about on line sex and you know take away sex that you get delivered to your door, carry out sex, is that once someone turns up, they are not bothered whether they use condoms or not and in most cases that unless you insist that they won't.  So I think it's one of the major vectors and loci whereby HIV is spread in the gay communities because people don't care.  It's online, it's almost like virtual sex. It's not quit real somehow and it's a great danger, and it's a growing danger.
