So about that. My dad is 5’3 and married to my 5’ mom. My brothers are around 5’4-6 and have always had girlfriends. Unfortunately for my example this height is average for men where we come from, over here almost nobody is 6’ tall, but maybe OP would have more success with certain ethnic groups (not just Southeast Asians and certain Arabs) although frankly I don’t know how one can target a specific ethnic group without it seeming creepy.

The point is this whole 6’ obsession, if not height obsession outright, seems very Western. And even if the same concept is prevalent in other parts of the world it might help if the average male height there is significantly lower.
