One would guess this would also apply to gay men.

Actually, it would apply to everyone and not just through sex. Take a bus to work and you’re sitting on a seat that hundreds have sat on and you pat the seat with your bare hand and then wipe your nose, rub your eye or pick up your danish and put it in your mouth. There’s DNA on counters, doors, phones, pencils and everywhere.

They're not talking about just DNA. I believe it has to be 'live' semen...not just DNA.

You would not believe what a human fingerprint looks like under a SEM (scanning electron microscope). I found it hard to eat for a while after I did.
