Just to clarify though, "not liking sex" is not the definition of asexuality. Asexuality is where you don't experience sexual attraction (and is therefore an orientation, or a lack of an orientation). Whether or not a person actually has sex is a choice and a behaviour, whether or not a person enjoys sex acts is a personal thing. Some asexuals don't enjoy sex or want to try it, other asexuals are open to sex and can enjoy it... even some people who are not asexual do not enjoy sex for various reasons.
