Opinion on a 63 year old man with 23 year old woman?

I am 63 and hooking up with a 23 year old woman for the past 3 months. Its amazing. We really got along at first and I made the first move and invited her for a cofee, and eventually proposed a hookup relationship which she wanted to try, and here we are.Obviously it won't become a realtionship but we only want sex so hope it will last.
