Honestly, I never liked the idea of her love being purely sexual. Why can’t we have someone who is about non-romantic love? Why does it always have to be sexual?

@Poptard  
Wasn’t Troubleshoes shown to be taller?

@Rokesh
 
In the blog, Celestia is straight as well, but she has the unfortunate traits of being into taller stallions while also being the tallest pony in the country.

@Amagan  
Blog, no mention in either comics or the show, naturally :P

@Heterodyne  
In the blog, the IDW comic, or in the show?

@Rokesh  
She’s confirmed as being basically Pansexual, but monogamous with Shiny.
 
Quoting, “Cadance = If it’s legal and ethical…”

Wait no… She is a princess of love, so she should represent all love as equally beautiful.  
Flurry Heart?  
Silfoe, I need your help :P

Definitely a lot of passion going around in this royal marriage!
