So.. some gay men hit on you. How old were you? Did those men who initially got you interested in interviewing more men back off when you said you were not interested in sex?
Out of the two dozen men you interviewed, absolutely none of them came across as stable? Have you ever met a homosexual who did?
How do you get so many homosexual men to come on to you? Two dozen is an extraordinarily high number, for a straight man. Can you think of any reason that possibly would result in you attracting the seediest homos in every city you go to?
I don't want to come down on guys in general, but if I had to judge heterosexuals strictly on men who have come on to me, I'd have a pretty dim view. I find that in certain settings, if you spend a little conversation or allow a man to buy you a drink, somewhere along the way sometimes a feeling of entitlement pops up. It really wouldn't surprise me if that attitude was also prevalent with gay men.
For the record, I also have met gays and lesbians in Australia... did you catch any drag shows? Honestly, no matter how you feel about homosexuals, if you can't find humor in a drag show in Sydney something is wrong... :-)
