Share 'I don't want a second handed girlfriend?'

I was walking home with this Chinese dude and he was telling me if you date and live with a your gf for one year. Later on you discharge her, then it very hard for her to find a 'good' bf in the future. Why? because Chinese men don't like 'second hand' gfs. So how many hands have your previous gf/bf been used by other men/women?
