A lack of sexual attraction. How straight males feel about men for example. They do not. An asexual person can fully enjoy sex and desire sex with other individuals however they arnt not particularly aroused by peoples image. Can be aroused by peoples actions and have fetishes and kinks.

An asexual is someone who does not experience sexual attraction. Many asexual people experience attraction, but we feel no need to act out that attraction sexually. Instead we feel a desire to get to know someone, to get close to them in whatever way works best for us. Sexual or nonsexual, all relationships are made up of the same basic stuff. Communication, closeness, fun, humor, excitement and trust all happen just as much in sexual relationships as in nonsexual ones. Unlike sexual people, asexual people are given few expectations about the way that our intimate relationships will work. Figuring out how to flirt, to be intimate, or to be monogamous in nonsexual relationships can be challenging, but free of sexual expectations we can form relationships in ways that are grounded in our individual needs and desires.
