Sometimes I see couples with a 6'4+ man, and his girlfriend is always like 4'11. It makes me wonder if they just like kids. Of course, height is out of people's control, but I do think couples should be in a similar height range. I wouldn't feel much romantic attraction if I towered over a man simply for ego purposes, or if he was so tall we couldn't comfortably cuddle. There's gotta be a good medium.
