I often wonder about the NASA teams who man the Space Stations for extended periods - often months at a time. After all, I find it enough of a challenge to fight my natural urges for any more than a day or 2. Not only do they have the added problems of being monitored by Mission Control 24/7, allowing them little or no privacy, controlling the release of semen must be a nightmare. I can only imagine they have a supply of condoms on board for that purpose.
