Demisexuality is the sexual orientation of a person who does not experience primary attraction, the physical or sexual attraction, but does experience secondary attraction, deep emotional attraction. Like asexuals, demisexuals often don't have sex due to lack of attraction but they can and some do, when with a person they most likely already have a deep emotional connection with. Demisexuality means lack of physical or sexual attraction but it doesn't necessarily mean lack of sex drive or that demisexuals don't crave companionship or a relationship, that might or might not involve sex. Demisexuals can be aromatic, heteroromantic, homoromantic, biromantic, or panromantic, very much like asexuals can be. On rare occasion a demisexual person can be attracted to someone sexually but usually it is after developing a strong friendship or relationship with that person. This is no way discards someone of their demisexuality and is important to remember.
Friend: Demisexuality? What the heckles is that?
Demisexual person: It's basically sort of like being asexual but with more emotional attraction and also I might have sex if I find the right person and I want to try it.
