Wait, does that even exist? I don’t think I have ever seen one.
I have seen BL with other disabilities though. If you are interested, check out ‘I hear the sunspot’ or something. Too lazy to check the actual name, but it is along this line. The main character has hearing impairment. The portrayal of hearing-impaired person who is not totally deaf is pretty interesting. Be warned though that the amount of misunderstanding in this manga is so damned high that sometimes it is so frustrating to read. Still a pretty solid BL overall.
Sorry that I can’t give you the recommendation you asked.
Okay,the semes in these stories might not be exactly how you want them to be but I personally feel that these boys are a little ~cuckoo~ in their brain, like, some are seriously lacking in communication skills or any expression of their own desire like autistic people ( no offence intended) and some are mentally ill like fuckboi Yule from Hogu hagyeongsu and that seme boys next door. Try reading if you haven't already.

Since my request didn’t get a response last time: Recommendations for yaois with a semi who is mentally challenged or has a learning disability?
