For me it's all about getting rid of any traces of my DNA. My passport won't hold up to any real scrutiny and my fingerprints belong to a special forces soldier who is MiA, presumed dead, following a helicopter crash during a covert mission In Nicaragua. I therefore either take the condom with me and incinerate it to get rid of my baby batter or I insist the girl swallows the lot. That way I fly under the radar
