that's an interestingly positive post cat which really got me thinking. I have often chuckled to myself over the strange fact that the best sex of my life was when I was in a monastery for a few months. It had to be limited to a tiny few minutes and inaudible at that (paper-thin walls) after a busy day of prayer and work.
Don't take me too seriously on this but all that prayer and work was in a strange kind of way fore-play on a grand scale.
Sex can never be fully satisfying unless the whole person is involved. I think the reason pictures are addictive is because we look at a picture and yearn for all the aspects of the other person which are not IN the picture at all and so immediately have to look for another one in the vain hope of finding that missing ingredient - just like the alcoholic does with his next glass of wine and then his next ad infinitum. (Same with drugs and gambling of course.) The person is focussing upon the very thing which we hope is there but isn't. It takes some turmoil and repentance to recognise this. In heterosexual men it seems to happen when they have experienced a mature loving relationship. For the BL this might never have happened. Our frame of reference is immature and inexperienced.
One strange thing about prayer though: and this was such a problem for me in the monastery. Prayer heightens rather than lessens the desire for that impossible loving sexual relationship. I rather think this might be one reason why some Christians get so hung up about it. I have no easy answers for this dilemma.
On a final note, the computer is a strange phenomenon. Slightly akin to a musical instrument in that we press keys to do things. Playing the keys is in itself a creative activity except that, instead of the sounds that come from a piano, we get pictures, websites, colourful things and opinions etc. I think it's going to take generations for people to come to terms with this world-transforming invention and to understand all of the psychological implications.
