Hi MaxandRebecca,
We are 47 (F) and 48 (M) and have in our profile (I think) up to 55. But that's nebulous. We just look for folks that have kept themselves in shape as much as possible.
Attitude and Personality are as important as looks to us.
We went to a dance recently and it was kinda cool to see some older folks (I'd say in their late 50's) there. There is a market for you!
