Everyone has made some very good points. And you are amazing at making yourself understood (I'm afraid I'm not so good at that, but here goes....)

Please do not take offense at anything I say...

When I was young and I had not had a boyfriend, I also wondered what the heck all the fuss was about. I did not get it.

The thing is, if you haven't had sex, (or found anyone that you WANT to have sex with) then you wouldn't have any kind of reference for it.

Perhaps you need real emotional attachment before you are able to feel desire. This isn't wrong. There is nothing wrong with you for feeling this way...

Just a thought...
