The Yaoi genre is, at best, a sex fest with deeper discussion about sexuality as a background.I LOVE how she discusses the impact yaoi has on her understanding of sex and relationships as a queer.
Most works in the Yaoi genre won't teach you how healthy relationships work. This goes for gay girls, boys, non-binary folks, and even straight people. It's straight-up fantasy and wish-fulfillment (save for VEEEEERRRY few mangaka who are actually capable of delivering realistic relationships)
