Question

One word for the person who is sexually not interested but pretend

Answer 1

Asexuality is the lack of sexual attraction to others, or low or absent interest in or desirefor sexual activity.[1][2][3] It may be considered the lack of a sexual orientation, or one of the variations thereof, alongside heterosexuality, homosexuality and bisexuality.[4][5][6] It may also be categorized more widely to include a broad spectrum of asexual sub-identities.[7]
Asexuality is distinct from abstention from sexual activity and from celibacy,[8][9] which are behavioral and generally motivated by factors such as an individual's personal or religious beliefs.[10] Sexual orientation, unlike sexual behavior, is believed to be "enduring".[11] Some asexual people engage in sexual activity despite lacking sexual attraction or a desire for sex, due to a variety of reasons, such as a desire to pleasure themselves or romantic partners, or a desire to have children.
