I'm 5'7", which is above average height for women in America. I tend to like guys taller than me, but it's not a deciding factor really, because I've liked plenty of guys who were my height or a couple inches taller without any thought to their height. The ideal image in my mind is like 6', but that's not reality, lol, I'd still easily go for a guy shorter or taller than that.
Really anything above 5"7 is attractive to me, I'm only 5"1 so yeah.
But I will say that a guy who is really tall, like 6 feet, is automatically more attractive just for his height, as long as he has broad shoulders and isn't stick skinny (or fat either). Gets me hornier.
I know several guys like that, over 6 feet tall, big (broad, masculine body, not skinny but def not fat). Ah..sexy.
Is it necessary for me to be attracted to you? Absolutely not. But am I more likely to be attracted to you when you are this tall? Very likely.
