Cryosexual (noun): A person who does not have a sex life, whether due to lack of interest, lack of opportunity, or personal choice. Being cryosexual may imply a prolonged or indefinite period of sexual inactivity. Often used humorously or self-deprecatingly. Not necessarily the same as asexual.
"After three years of focusing on work and gaming, he jokingly called himself a cryosexual."
