here's why 6'2" is (should be considered) the perfect height for a man:
1. unless you're basically legally a midget, he won't be too tall for you.
2. unless you are an amazon woman, he will be at least 2 inches taller than you.
3. any girl can wear heels with her 6'2" boyfriend. short girls can wear anything from flats to 6" heels, and tall girls can also wear flats or heels. hell, even a 6'2" girl (if there are any) can at least wear flats. and 6' girls can still wear heels! heels 6' girl!
other heights just don't work (you [i] could probably make a good argument for 6'3"). 6'4" or 6'5"? way too tall for any girl between 5'1" and 5'8". you can still wear tall heels but it won't even put a dent in that span. also, making out is only comfortable in certain positions, and why limit yourself to certain positions?
i don't think i even need to bring up the reasons why shorter guys aren't universally the perfect height. but i will. flats your only option? no thanks! shorter than me? i don't want you to have to look up to kiss me. don't worry, there is nothing wrong with lesser than tall guys. they have girls to date. they are just not universally the perfect height.
in summary, every girl has a range of heights that she can work with (or a different height she might prefer [or example, my EC is probably approximately 6ft and some change]), but i am saying that 6'2" is the height that any girl could work with. universally, the perfect height.
