You know what, I have a friend who use to change his girlfriends on monthly bases. I was surprised that how does he is living such a live and how can he make a girl as his girlfriend.
So, I asked him and he responded that he has an account on dating.com and thanks to that website he has got plenty of options to choose his girlfriend.
After his recommendation, I registered myself on the site and made four to five girlfriends on the site as well.
