I get youuuu I also have that problem. I'm a diverse reader but when someone asks for recos I just end up blacken ang chicken out lol. I usually just say the mainstream like Eleceed, S-classes that I raised, ORV, TCF and things like that but I throw in a couple really great villanes tropes like, I became the Male lead's adopted daughter and I'll become the matriarch of this family. When I have someone curious about BL I introduce them to somethings soft ang light first like Here U are and cherry blossoms after winter and from there I give them omega verse and things like that so they can explore
When a cool person asks you what you're reading rn or what your favourite manga/manhwa/manhua is whats the one you say that you feel most comfortable saying or makes you sound cool? The only people that ever ask me are my guy cousins so I usually say chainsaw man or jjk (i mostly read josei/shoujo/BL/GL). When a girl asks I get anxious so i just say what i'm reading rn and they ALWAYS say "oh I haven't read that one yet. and it CRUSHES ME.
