Another stat to consider is percentage of homosexual men in a population. By country they are likely to be fairly similar, but most countries have cities that disproportionally attract gay men because they feel comfortable there. The proportion of lesbians in a population is almost always much lower, so a city with many gay men will be much better for straight men than the stats may suggest.
So. Check out places like NYC, San Fran, Amsterdam, Vancouver, Cape Town, Sydney etc. etc.
