The more I've dated the more I know what I like and what I don't. Frustrating because I have BFF girls that I adore but the spark isn't there. I've also had girls who all we had was spark. Is it too much to ask for to want both?

I can relate , as I feel that way sometimes. Though I know if I could have a simple no-strings "thing" with a hot (to me), young fella, who can hold his own in conversation , I'd likely perk right up.
It's the complications of day-today relationships that cause the urge to hang back and disappear ...

I agree

sounds more like your apathetic to any relationship that doesnt meet a high standard than asexual my asexual friends like company but sex just does not enter the equation never has never will as one put it

In my marriage, I was beginning to feel like an asexual, which is why I got out. It wasn't me, it was the lack of interest on my wife's part. I finally started saying Why bother? That's when I knew there was something really wrong. Because normally I'm a horny bastard.
