Mommy Tammy,
I don't think 46 is too old. Age can have some impact on sperm quality but it certainly doesn't always-just like women and eggs. I'd consider having a semen analysis done if you decide to go with him just so you don't waste any time, yours or his. Before I met my current donor, who ran in my same circle professionally, I talked to a couple of guys online. My mom and OH thought it was a little weird and I know that to most it seems pretty creepy. However, I also know that in talking to them, they were really nice guys, both gay men who wanted to help out a lesbian ttc. If I hadn't experienced talking to them myself, I might think it is creepy but having done it, there are some great men out there. I know that Em will also attest to the fact that their are some creeps out there too so you have to be careful. If your OH isn't willing to go with you to meet him, maybe you should consider taking a friend with you, just for your own comfort and safety. Good luck, I hope it turns out to be a good match!
