Dear Ah Puppy,
What happened?
Actually, it really depends. Some girls like the bad type, some
like the good type, and some even like girls. 
Ah bengs tend to attract more attentions due to their wayward
behaviour. Hence, there is this mentality that sticking with ah
bengs will be more fun.
Good guys usually portray the boring lifestyle.
However, times are different nowadays. It is no longer hip to be an
ah beng.
You do not necessarily need to be an ah beng to woo girls. Try to
make their times spent with you enjoyable. Give them the security
that they need.
Regards,
Uncle Agony
