Very well said Op. Don't remember a bad session with a lady 35+ and don't have a memorable experience worth mentioning with a gal <25 but stopped seeing the young ones years ago. Sadly I'm also at the point I don't find a 21 year old sexy - my kids are older than them and there's no way I'm believing a hot 21 year old really wants to be with me. Said it before, will never understand the fascination with the young ones on the Welcome Wagon.
Older ladies know what they want both personally and sexually. They care about and know how to turn a guy on and take pride in making a John feel like more than a few bucks.
