Or it could be that mothers don't spend as much personal time with later children. Either way, the study is pure conjecture, and doesn't explain my OLDER gay brother.
I also think this is garbage retrospective analysis. I do feel that some of the many factors that lead someone to chose this could have something to do with economics... now some might say this is silly. However, I think that physiologically the gay man will find their pleasure and then economically it seems less taxing than to get married and raise a family. I think under these circumstances it's easy to recruit gay men. I base this off some of the gay men that I've met in places like college and liberal circles that I've come across - Also some of my gay family members.
Good point. My wife's brother is gay and he's the oldest. The whole family knew he was gay since junior high. LOL
