I'd be careful with it. It's become another trope for fetishizing Asian women, and Asian sex workers have been talking about it for a while now. that said idk apparently I make a similar face without even thinking when I'm fucked right, just not the performed, exaggerated version in hentai.

so maybe not inherently racist (?), I'm just a white girl who googled it. just be careful not to fall into that or attract the wrong kind of people with it and listen first to those it can harm.
