We are fairly infrequent on the sex front, it's more a lot of cuddling and playing nowadays. She fusses over me, doing up extra buttons on my shirt, or turning down my collar so I look "nice". She worries that since my diet change I have become too thin.
Like yourself, my GF will be well looked after when I pass on, but she hates any discussion of the topic.
I sometimes get the feeling we become father figures to much younger women. My GF uses me as a sounding board, and turns to me whenever there is a problem. While she will travel with female friends in a minibus on excursions, there is no way she would get on an aircraft without me, or drive on mountain roads.
She got quite scared on a recent trip up Doi Mae Mon, to see hydrangeas in bloom. Started a bit of back seat driving, I put a stop to that by asking if she would like to drive instead. When we were back down on the flat, she thanked me for getting us down safely, and said never again. Which will last as long as her next itch to go somewhere.
