Time to blow my own trumpet I guess. Tall, blonde, intelligent (member of mensa since my teens), practical and virile are all applicable.

I've never had children of my own, having spent a long time enjoying myself, but arrogant as it may be, I don't think my genetic material should go to waste by not passing it on to future generations.

I'm not married (was in the past), so no complications there. All we need to do is agree how we want this to go and assuming we do, we can make it happen.
