I don't think it would be right for me to even fantasize about having sex with anyone (regardless of whether they be man, woman, or child) that I'm not married to.

I personally have a different view about fantasy.

I am comfortable with sexual fantasy outside of my marriage as long as it is fantasy (ie: something I wouldn't actually DO in real life AND something I'm not COVETING after doing).

In this respect I avoid fantasy involving real people. I do this to avoid the temptation to covet them in day to day life. Most of my fantasy revolves quite successfully around imaginary boys and I'm quite comfortable with that.
