I will say that making love is very different than having sex, although both end with the same result.
Making love to me is an event. It takes a while. You need to start the day right, do loving things all day long. It can be as simple as leaving a note in a place your love can easily find it, making a quick call to say "I love you" or, a quick pat on the butt. It can also be a passionate kiss and a "can't wait to see you tonight" It can also be elaborate, with a movie and dinner, or a few drinks at the local club, or having flowers delivered, just because.Making love is two people that have genuine deep feelings and commitment to each other.

Having sex can be between 2 that have deep feelings of love for each other without all the preparation like I sighted above. They are just hot for each other at the time and it was unplanned. Just good sex with someone you love deeply.

It can also be between 2 that have no connection, like a one night stand. No emotion, no passion, no commitment and no love. It is an act between 2 that had no prior planning and have no long term connection. It is almost animalistic in nature although it isn't necessarily brutal or abusive.

I won't go in to the psychological damage that can occur from the sex for just fulfilling carnal needs can do, but sex without love is not healthy.
