I need unbiased vision on this:

1. after 60s, how do a men react with 18 year girls or like that...does he behaves like daughter or sexy women to F

2. do after 50, women feel sex interest? ... and how she reacts with young men? ..

any experienced people there?

You as a man how do you feel about women? Let me ask differently : if you were in village in Nepal , as in city like Kathmandu and once you were out of country in city like NY or DC or Sanfransico as your mind works it may be the same just slightly different. I mean mind is same but the penis may erect for couple minutes only just in thought.
