A man who labels himself a "donor-sexual" claims to be a virgin, but also claims to have fathered fourteen kids. The California sperm supplier claims to have never actually had sexual intercourse. I am guessing one of his arms has more muscles than the other.

Trent Arsenault has actually been giving out his sperm free of charge to help couples that want children.  The FDA is not to keen on his generosity and have issued cease-and-desist order.  Arsenault claims to be disease free and says he just wants to help people.  He markets himself and his sperm on line at www.trentdonor.org.

The giver of goo said, quote:

"I've committed 100 percent of my sexual energy for producing sperm for childless couples to have babies. So I don't have other activity outside of that."

I guess you could call him "A Jack of Just One Trade".  Emphasis on the "Jack".
