Missing link

I have been thinking for a while now, quite a while, that I really don't know what a "Relationship" is.  The theory is that it is when you are with someone that you like who you are having sex with.  But then it all breaks down.  I think that there has to be more to it than that and my inexperience with such things is becoming clear.  It has been so long and before that and before that.  I think that I am missing something.  

I think that my friendships are relationships without sex and then I have a hiccup— there must be more to it than that, I must be missing something.  I just don't get it?  I love my friends.  I do stuff to make their lives better, or I try to.  I talk with them on subjects we share, I do stuff with them.  Just no sex, and I wonder am I missing something.  There must be something more to relationships than just that, there must be because I do all that with my friends, but I can't seem to inspire anyone to have a "Relationship" with me.

And PrettyKitty, I said I have been thinking about this for a very long time.
