Is it normal to not be attracted to bf?

My bf and I get along really well. We have been together for a very long time. We are like best friends. We enjoy the same music and activities, we are both health conscious and have the same religion and ideas about raising children. (all which is very important in a serious relationship) The thing is I am not attracted to him at all. I was when we met but he looks totally different now. I know looks are not everything so I can get past that. But that aside we don't do anything sexual and if we do it ends up being a horrible waste of time. Sex is not something we are on the same page about at all. Anything we try to do is always awkward and really really bad. It's horrible so I avoid it all together. Sex is also a huge part of a serious relationship. I'm very attractive and everyone has said since we first met that I can do much better but my question is is it normal to have a relationship where you don't have any sexual interaction?
