I donate my sperm everyday for my pleasure, why not do something good with it?
I'm a Nurse . student, I'm willing to donate my Sperm to spread my genes. I know I may not be a "Genius" but at least I know that my IQ level is good enough to be called intelligent. Your son maybe even smarter than me if your wife or the egg donor is smart enough too.
It would be an honor for me, donating my sperm for you. I would love to keep in touch with you in the future in see the evolution of YOUR child.
