We're going through the adoption process now. We've attended our classes, had our paired, individual, and network interviews, passed our DMV checks, criminal background checks, employment verification, filled out dozens of pages of questionnaires, found respite providers, and I forget what else. We are now in the "matching phase" where the county shows children's files to us and our files to children's social workers (and sometimes children) looking for a "match". Obviously I haven't actually experienced having a child but when I see families I sure want one.
I've talked with many who have adopted and they are almost all very positive about it, even the ones who have ended up with what most would consider nightmare situations (drug-addicted runaways, multihour temper tantrums every day - these people are mostly adopting older kids who have gone through serious trauma).
I don't think women are more open to adopting; I think they just want children more - especially very young children where teaching and mentoring aren't good substitutes.
Hope it all works out for you, Panda. It's not clear what you've been doing and I don't intend to stick my nose where it doesn't belong but if you've been trying for 2 years without results I hope you're seeing a good fertility doctor. After that long there's a good chance of a biological issue. Some fertility issues are easily fixed and some are insoluble - I would want to know where I stood on that before choosing adoption, especially if having a child that looks like me were important to me.
