Am I tripping, or is every dick in Yaoi/BL circumcised?

I've been reading Yaoi for years, and I just realized something.

How come I've never (not even once) seen an uncircumcised dick?
Like... seriously. Not a single one.

I know a lot of older works were censored back in the day, but nowadays a lot of series get uncensored editions or are redrawn. And even then... everyone is circumcised. At least that's what it looks like to me.

Is it really that common in real life? I'm not a guy, and I'm kind of asexual and aromatic, so I don't exactly come across penises very often... or at all.

I swear I've read 100+ BL series at this point, and I genuinely can't remember seeing a single clearly uncircumcised character. They don't even mention it.

Has anyone else noticed this? and what do ya'll think the reason is?
