Im a dude which means if someones an adult im not likely to shy away. Realistically there is a point where someone younger than me is not going to be attracted to me or the commanality factor is not there or our lives simply would not mesh. Granted im married so this is all theoretical alternate univers where I was not. Similarly when it comes to older its likely to be more about looks. We all know some folks that keep themselves fit and if someone is hot they are hot. Now the limiting factor there is im not exactly fit and you have to be realistic in expectations. Anyway I don't think its about age when it comes to attraction. Its physicality and personality meshing.
