You know I met a horse girl on tinder and I went on a date with her where she let me ride her horse and it was actually a ton of fun. I can definitely see why women get really into it considering how fun it was. Think of the way so many women talk about dogs and then consider how a horse is even more investment and money and work.
Honestly I'd be more worried about women fuckint dogs than horses. Barns are smelly and disgusting and horses are fucking huge I dont think very many people would risk getting underneath one to get smashed under its hooves or have their vagina busted by a 18 in dick. Besides 1/2 of horses are females and most males and folded, I think the word is, aka neutered.
