It's your call, but think very carefully about dating coworkers in general. These situations can get kind of sticky. The worst outcome, of course, is that you become so uncomfortable that you have to change jobs. Our economy is trashed right now (Iraq war spending, don'tcha know), so think carefully about whether you want to proceed and if it's worth it to you. Add to that you must share STD information with this person, and if it doesn't work out, somebody in your workplace knows very sensitive and personal information about you.
