Asexual representation is few and far between, whatever form of media you look at.
Many characters deemed as "asexual" are quite frankly just offensive stereotypes, poorly written, or never explicitly stated to be asexual.
While asexual characters have been making more appearences in media, they account fo an incredibly small percentage of LGBTQ characters.
GLAAD's 2023 LGTBQ media report, Where we are on TV, counted 8 Asexual characters in TV, an increase from 6 of the previous year. This was ONE PERCENT of LGBTQ appearing on screen.
