A guys point of view on this one...
I can't imagine anything worse !
But then thats just me. Shrink we saw last year came out with "You have to understand that M doesn't separate sex and intimacy"
I still wonder what that really means. I don't feel that I am suposed to go and somehow work out how to separate them, I jst feel that its a very intimate act. Kissing similarly, very intimate act physically expressing feeleings, seeking closeness & sharing pleasure. I have to feel close to, and attracted to someone to kiss or have sex with them, i.e. be emotionally or phsycally intimate.
I can be emotionally intimate with someone (verbally expressing feelings) without being sexually attracted to them, so there's intimacy there with close friends, family etc. but totally no interest in being with them physically.
Dunno where that all fits in with the fantasy (not one of mine is all) but I wonder if it is at all related to picturing someone you love as a pornstar or something.
Just had a thought ! :
I reckon surprise him with a huge mirror on the bedroom wall oneday ! (diy packs of self adhesive mirror tiles ?)
Then he can see himself as the the 'other guy' in the mirror ! could be a win-win-win idea

Now there is where it resonates with me after all, I like mirrors

hehe
