Saw a poll once where 52% of college males said they didnt believe in sex without love... and the other 48% told the truth.
To be truthful, I would have to say lust because love doesn't really exist. You can never truly know a person.
lust doesn't comes always with love, you see a hot girl passing by.. you will feel lust for her but love comes with lust...emmmm
Love is the foundation of being a true person. Lust is something you want to satisfy yourself and some thinks that you are loving a person because of your personal satisfaction and that's not true at all.
