I've done both! And, there is something positive about each experience. Younger men are enthusiastic, exciting and excitable, exuberant, energetic and refreshing. The young man I dated had an element of surprise meaning, he was easily enthralled, spontaneously happy and unassuming. A joy to be with.
The older man I spent time with was calm, genteel, quiet and very self assured. When with him, I felt an inner strength and bearing which, I believe, was the result of being older, having experienced life; the ups and downs, and being a bonafide adult. His presence was serene, sensual, appreciative and subtle.
There is something wonderful about both; which translates into this: We all have great gifts to bestow upon oneanother; "plusses" which come from our own individual experiences and personalities.
My answer: BOTH
