Aging for men is not the same as it is for women. Older men can still be sexy ,handsome and desirable by younger women. Older women are just older women past their prime and put out to pasture. Your a man op so you will never really be past your prime.
This is not true in all cases though. It depends I think on the woman and if she continues to really take care of herself as she ages. There are older women who look beautiful but the reason that many don't is for the fact that they just stop caring period. The ones that stop putting on the makeup, stop caring about their weight, those are the ones that become bitter and look like they are ready for pasture as you term it.
