LMAO at you crappin your pants 'cos that is exactly how I feel! Talking to real people about it, is much more difficult than dealing with some frozen sperm on a stick! I now know why people sit on anonymous donation waiting lists for years. - it is much less confronting. What Humphrey says is the same as what the AED people say about egg donation:

... would want a donor who is doing it for purely selfless reasons i.e. to give someone derserving and unable, the chance at parenthood. Not someone who wants to "extend" his own family.
But at the same time, you don't want to be too suspicious. Just as there are some young women who are very selfless and want to donate, there are probably men like that as well. And remember for men donating is very easy and they could do it every day of their lives if they wanted. some women have the attitude, "well I am not using my eggs so why shouldn't someone else" so there are hopefully men out there with that attitude as well. Just be clear about what you want and make it clear to them as well. I think taking it in your own hands is great.
