I love you as long as we're still havin sex

It's slightly unnerving to be neck-deep in a relationship and realize that it wouldn't survive a week without sex...one of these things that knock me off my cloud to come crashing down to earth. Same kind of effect as when I learnt that marriage didn't last forever, love was in fact not unconditional, and that people- whether friends, family or lovers, do drift apart.

It's not ideal.
But maybe its just the way things work.

Maybe being idealistic about these things isn't a great thing, and the challenge is to channel this idealistic energy into motivation to hold oneself to higher standards - I can't figure out if that's okay or if I'm selling out.
