I think it really depends on you, and your partner, and your joint interpretation of cheating. Some people say it’s not cheating unless it’s penis-in-vagina sex. Others would say that showing any form of romantic interest in another person is cheating. I always tell couple that they need to discuss their boundaries openly. But at the same time, if you were to engage of any kind of sexual activity outside of your relationship the best possible place to do it is with a legal courtesan. That way you know you’re safe and you won’t be bringing home any diseases. You also know that the ladies are professional and will not be calling you the next day or causing problems with your significant other.
