Open Question: Should I cheat on my girlfriend with a femboy/gay guy?

[feedcrawler]

I have a girlfriend of three years who I love very much. Very attracted to her and our sex life is very very good. However since I was younger I have had an attraction or fetish(depending on how you look at it) for Transgender men to women or crossdressers. I always have looked and pictures on the web and recently decided to post an add on craigslist. One of the response was from a fem man who is willing to fullfill every request and fantasy that I have had since I was Younger( Pantyhose, leg, foot fetish etc...). Should I take the chance to do it and meet up with the guy to play out all the scenarios I have been fantasizing about? Or just write it off as a sexual fetish and not do anything?
