Oh no I dont feel that way at all. But as far as what makes it something that fulfills my life I think it would be the emotional aspect of it that does it. Trust me, I like sex just fine for the physical aspect. Some times I like it too much and tire out my boyfriend with the amount that I want.
For a long time I thought that all I needed was the physical side of it and I didnt understand why I wasnt enjoying myself as much as I had in the past. I didnt get the same thing out of it until I was in a relationship with someone that I really love. Love between partners makes good sex great sex.
