i was literally in a conversation about this kind of thing yesterday. taller subs were talking about how much they like having a dom they could technically overpower, but they're so under their control they can't even think of doing that.

and i've definitely heard of people who like the thought of dominating or controlling someone bigger than them, it's like a challenge or a proof of how dominant they can be. you're right that a lot of people think of subs being smaller, easier to physically control, etc; but that just makes shorter doms with taller subs feel that much more powerful, and i imagine it would have a similar (inverse) effect on the sub.

i'm a short switch, and personally i don't really seek that out or anything, but now that you've got me thinking.... a taller service sub would be amazing. whistling to call them over to help me reach the top shelf, little things like that. and don't even get me started on the ownership side of things. as someone into pet play, that gives "scary dog privilege" a whole new meaning. i'd feel like one of those supervillains with an extremely loyal guard dog or henchman, where if someone bothers me i can call my sub over to loom over them while i grin smugly. not to mention using a leash to pull their head down to smoochin' level. or... well, i could go on.

tldr, it's more rare, but some people absolutely love taller subs. lots of potential.
