For mature couples, sex is a way to show compassion, and intimacy, and enchance chemistry. However, nowadays, one can go to a brother and hire a hooker. That kind of sex is an empty shell. So i guess it all depends who you have sex with. If it's with someone you love and care deeply for, it is definitely taking it to the next level. But if it's with someone you only have know for a week or picked up at a party, etc, Then it doesn't mean a thing.
