It's simple, when u are dating. U want a naughty guy, one who is exciting, one who is romantic, one who gives you excitement sexually and physically. Then when u get married, you want the dull one. the one who is safe and the one whom u know will be stable.
It's really a case of you being the right thing at the right time.
Normally the girls that are after such guys are no better than selves and most likely are into quickies, etc etc..... as they say birds of the feather flock together.
