Asexual

Asexual, often abbreviated to ace, is a sexual orientation defined as a lack of sexual attraction. Sexual attraction is defined as the desire to perform or receive sexual acts from another specific individual. However, asexual individuals can still have a desire for sex, but just not toward another specific individual. It is important to note that asexuality is different from celibacy or abstinence, as both are voluntary, but one can be celibate or abstinent whilst still being asexual. It is also important to note that asexuals can still experience other forms of attraction; for example, romantic attraction. Asexual as an umbrella term can refer to all identities in the asexual spectrum.

Asexual (or in this instance, ace), also makes up the second, third and fourth letters of "Pacebi". However, the "a" can be considered part of the "Pa" (pansexual) too.
