it happens.
long non-traditional hours, over indulgence of alcohol, spouses who aren't "in the business" and can't always related, and even worse when you don't want to burden them with what you were exposed to (mentally, not physically), and the fact that we are (in general) an incestuous bunch who tend to spend waaaay too much time together, and you see what happens.
That all being said, I know quite a few happily married people, who don't cheat on their spouses. They have been married for 30 years, sometimes to a person in EMS, other times to someone totally out of it.
Have I had one night stands before? yes. Have I had flings with people in EMS? yes (but never while at work). Have I dated coworkers? (embarrassingly) yes. Have I gone out with coworkers and had too much alcohol? pleading the 5th on that one.
Infidelity is one of those weird thing that isn't local to EMS. if someone is going to cheat, than they will cheat; their occupation or career has nothing to do with it.
If you are single and want to have a string of one night stands, go for it. sex is a great stress relief. Sex with coworkers is generally not a good idea, because it very very rarely stays secret. Alcohol is used for stress relief too, in the short term, but tends to have long term consequences. Many business men use it as well.
