I have taken a different tact: I have been totally honest with my significant other(s), and have disclosed my hobbying. It then became their choice whether or not to stay in a relationship with me (or to get into one in the first place). I simply was not going to compromise my reputation and integrity and put myself in a position where I could be called a liar, cheating bastard, etc., etc. In fact, I am in the process of writing a book, and my preliminary title is "Are They* Worth the Lie?" *They being women of course. Probably never finish or publish the thing, but you get the point. What are you prepared to sacrifice to get laid or satisfy your desires? Remember Arnold Swartzenneggar, John Edwards, etc., etc.? Perhaps the questions that should be asked are associated with why men cannot be honest with their significant other, or what, in fact, is wrong with their relationships that they need to hobby? Men are taking quite a hit these days. Honesty is a powerful tool to have in the box. I came to the conclusion that no woman was worth losing respect for myself. But that is a personal decision each one of us has to make.
