I think it depends on a certain couple. For example, famous ex-football player Fabregas is dating 46 years old women, while he is only 33 years. You should pick just a nice person,thats all. Nowadays girls are mad, my neighbour (24 y) is married on a girl (22y old) and he spotted this website

So this is just a waste of time for him, he got a nice job, high salary and he is clever enough to make his life good without girls, but sometimes we want someone in our life.
But I am out of relationships for more than 3 years, and I can`t say that I even shooked on this.. But, one thing I remember for all my life - I will have no any relationships with girls which are under 20 years old
