The writer may be right to some extent. In the 80s and 90s women preferred clean-shaven men but no more. Nowadays, they like men sporting facial hair. Look at todays heroes of Bollywood and Hollywood. You will get the msg. It looks macho. If a man likes and lusts for a woman and vice-versa it is because they have certain things that they themselves do not have and women have and vice-versa (Hope you understand!).
Pot-belly is ok but make sure you have a bit of broad shoulders and beefy arms. 8 out 10 women will fall for you.
