On another note that no one appears to have mentioned is that most 45 year old men that date 20 year old women are usually very wealthy and have much to offer a young lady who is truly to young to be secure in herself yet. At 37 I've often imagined myself with a beautiful young lady like the ones I used to date because I still remember the playful fun times I've shared with them in the past. I personally don't see anything wrong with it simply because I'm still a young minded fella who still rides dirt bikes, surfs and has a skateboard halfpipe in my back yard that I ride, i'm not ready to grow old yet.
