I totally agree with u as i feel the same too, tht sex is something that can happen only if u love each other and when u love each other you actually dont call it sex...but u say ure making love.When u love somebody u really want the partner to be happy rather than just pleasing yourself.When we just have sex we think only about our pleasure which i feel is Lust and not Love. When two human beings have sex its only a medium of pleasure and when the two of them make love its a bonding of two souls.
