Shopping for Mr. Right...'s Sperm

My wife and I are in the process of making a family.  Well, we had the consultation.  We are now uterus deep in books, BBT tracking, Period Watch 2013 and insurance coverage language translation.  We just found out our blood types and that we are CMV negative.  Now we are talking about the potential baby daddy.  We first have to narrow down the sperm bank.  But, of course, we are getting ahead of ourselves with what to look for.  Do you look for someone who looks like your partner?  Do you think it doesn't matter as the child will either look like myself of the "father"?  Do you just look for qualities that sound like Ryan Gosling?   That's our next post in our blog And the Vial Makes Three.
