We can't separate the Two.....

Lusty sex happens very casual and rarely;
while love placed a respect in your heart for your partner and remains forever (I hope so).

Intimacy bring both partner closer and felt loved and even that intimacy takes over by lust many a time.

So can I say that even intimacy plays an important role in Love making process..

Love=Intimacy=Love=Lust=Love again :)
