Since l have not had a realationship last forever, l have no point of reference.

Is called true love and deep caring, the sex comes with that. If you have to ask, you have never experienced that. It was a beautiful experience for 17 years for me.

I was still totally turned on by my husband after twenty years. Saw no indication of the attraction waning. In fact, the shared experiences and deep intimacy made relations with him hotter than I'd had/ would have with any other.

Depends on the person!

Some combination of keeping a promise through the rough times and working towards making it better. I think. I don't know anything though, my marriage didn't last.

I don't know. I've never been sexually attracted to another individual in my life. And I'm eighteen... apparently, according to media, t.v, and the conversations I over hear of my peers, I should be insatiably horny, but I'm not... and never have been. So I don't know honestly.

You just have a lack of imagination.
