Those of you for whom sex is a very important... shall I say vital? ... part of life, do you know why that is?  For yourself, I mean.

Is it because it makes you feel loved, wanted, attractive, safe, etc... or simply because it feels good?  

I ask because frankly, it's really not all that important to me these days, although I'd like it to be.  Maybe if I knew why it was important to some other people, I could explore that in myself.
