You should look for men who are divorced or widowers, because 41 is 41. I know you said “no discouragement” but perhaps that is one of your issues. People who lie to you to avoid hurting your feelings are not necessarily doing you a favor. Very few men who are not in the 2nd hand category or are themselves in their 50s or older are going to be even interested. Your other issue is most men who are not in those categories will feign serious interest just to screw you, after which you will be ignored. That is what a couple of my wife’s friends who are in this category often struggle with. So, my suggestion is to restrict your search to second-hand men.
