I realize you are just throwing ideas out there.....
But I think those are pretty pessimistic ways to look at it. We
all use fantasy, but not necessarily to escape, but simply to indulge ourselves. I don't know about anyone else, but I fantasize about sexual things that I don't particularly desire or perhaps
ever want to take place in real life. To say that men fantasize because they would rather be with someone "prettier" or "sexier" is a little unfair. Also, to infer that because we may not score high on the "pornstar" scale that we are second best is a little defeatist. Not to say that there aren't totally shallow men out there who will only settle for a Jenna Jamison clone, just that most men know that value is more than skin deep when it comes to someone you want to spend your life with.
Just my take on your advocation there.
