If you run a big sponsor program with a lot of sites and you have a few of them that are gay sites, it makes sense to hire a gay person to maintain and market them.
If you are not gay and you want to run a gay site, DO SOME RESEARCH. Check out the gay resource sites, webmaster boards and see what else is going on outside of the straight niche .... An open mind is crucial... You'd be surprise how many people who work in porn are homophobic and cringe at the site of one penis. Once quick browse through gfy.com will show you that.
