Ditto the others.
Sometimes a gelding will stay dropped a lot if they need cleaned and/or have a bean. Or they could just be dropped because it's so horribly hot/humid
Just an FYI, I only clean my geldings twice a year with some sort of sheath cleaner.
The rest of the times, I clean each one as needed with plain water and a wash cloth.
Using products too often to clean them, can destroy the good bacteria.
You're in Georgia with high humidity. The humidity can cause a horse to need cleaned more frequently, which my vet pointed out
