Sex is easily more important.. it's damn near a basic physical need. Don't know if I can say it IS a need because you can survive without it but it's pretty close. Love is more significant, and much harder to obtain. It's more valuable, and people appreciate it a lot more, but it isn't necessary. Don't get me wrong, it's really important, just not of the same importance as sex. A lot of people do need love to feel emotionally healthy though.
That's a good point, but that wouldn't be dieing of a lack of love. That would be dieing BECAUSE of the love they had for the other person, not because they didn't have love. If they didn't have love for that person they wouldn't have died, so really you could conclude that their love killed them. People don't just drop dead out of not having either sex or love, but to me sex is a necessity to live a physically healthy life. That's just me though.
okay but on the flip side to that, u if u dont have love, ur life could quite possibly end up miserable and unhealthy if not worse than it would without sex there are many people who go through life without sex and are just fine. old people (sorry for this example) go years without sex and are fine, but they always bring up the loves of their lives not the hot steamy sex in the back of a cadillac
