A person who identifies this way doesn't feel sexual attraction. They don't want sex with others. They can have other types of attractions. But they don't desire people in a sexual way.
There are many types of asexuals. Some want to have relationships with others. They may be drawn to other people in ways that aren't sexual. They may be attracted to others' looks. They may have emotional or romantic feelings. They may like to kiss, hug and cuddle. Other asexuals may not have these desires or want these things. They may enjoy friendships, but not relationships.
Asexuals are a diverse group. They express themselves in different ways. Some are private. For others, being asexual is a public part of who they are. Deciding how to identify and how to live is personal and complex. Every person must decide what's right for them.
