Is coming out worth it?

I'm a male, hetero-romantic and sex indifferent. I've been self identifying as asexual for about a year now but I haven't told anyone yet. Part of me wants to start letting people know but I think it will be too much of a hassle explaining it to people like my family. I sometimes think why bother because there's no way that people can really find out that I'm asexual and because my romantic relationships will be "normal" in the sense that they're male-female. Of course if I was in a relationship I'd let my partner know. I'd like to hear what you guys/girls think and if you've gone through a similar thing.
