Is aegon gay
If Aegon realised he couldn't have children, then I would suggest that Aenys could be the son of Rhaenys and Orys Baratheon - not through an illicit love affair, but with Aegon's full consent.
Like someone else said when an F&B character is gay Martin’s as subtle as a sledgehammer about it, we have no reason to believe that Aegon doesn’t just have a low sex drive due to depression, and even then he shows physical attraction to Daenaera and they do have 5 children together.
