bobquasit | Biting my tongue

One of the most common questions on Askville (and I'll spare you the poor spelling and/or textspeak) is "I had unprotected sex and my period is late. Could I be pregnant?"

I couldn't resist answering one guy (in the discussion board) who asked if his girlfriend could be pregnant:

Yes, she's pregnant. It's triplets, two boys and one girl. All three have brown eyes; one of the boys will grow to 6'2", and the other will be exactly 6 feet tall. The girl will be 5'7", and left-handed. Her favorite flavor of ice cream will be rocky road, while the boys will both prefer chocolate.

...

Look, we don't know. We CAN'T know. Have her take a test or see her OB/GYN.

And now I'm struggling not to post a question of my own:

I had sex and didn't use birth control. I haven't had my period...ever. Could I be pregnant?

P.S. I am male.
