Men: Have you ever donated to a sperm bank?

I wonder what the staff would tell me if I told them something along the lines of, “Er, you wouldn't happen to have some material depicting women crying as they're being spanked or penetrated anally, would you?”

Or what they would think.

. o O (Gosh I hope this sick bastard's infertile.)

Or Possibly - “I wonder what he's doing tonight???”

I've never donated, in my younger years I did think about it but never followed through.
