Shorter girls have no problem finding a boyfriend since us guys like to have a girlfriend who is shorter than us. It is kind of harder for short guys to find a girlfriend because usually, not saying all, girls instinctly want to have someone who can protect them so they go for taller guys.
This is rubbish in my opinion it's about the personality and beyond height. Any girls says no because your too short is not worth the time of day. And if this was the case all guys under 5,7 would be single.
