Is that changing? And I mean both the long term relationship and the expense having children part? The majority of my male friends are gay and while there are a lot of happily single men there's also a significant chunk who are in healthy long term relationships and a load who are actively looking.

I know less about the children side but I know a few gay men who have adopted, single or as part of a couple, and they described the process as rigorous but not unduly so. I guess this depends where you live, I'm in Scotland, which is supposedly the least homophobic country in the world (an extremely depressing fact) so maybe it's easier for gay men to adopt here.
