What happens when you have sex while on ecstasy?

I've heard that when you do, the experience will be so incredibly amazing, that when you do it while not on the drug, it'll never be the same.

A few of my friends have told me this, and I was wondering if it was true, as opposed to simply a rumor.

No, I'm not considering doing this, I'm just trying to expand my knowledge.
