Hi, buddy. I have the same idea as you, maturity doesn't necessarily have to be reflected in size! Men are generally taller than women, as long as the relationship is clearly explained at the beginning of the story. By the way, can you create a concept map for this "yoga story"? It's the style of your version. Many readers should also be looking forward to it, right?
This picture, perhaps an attempt by the creator, refers to the physical appearance of the character! I personally don't really like "threesome", but I prefer a story of two people, watching how Kelly breaks free from her shackles and how Dylan takes steady steps to conquer Kelly!
