I notice many girls tend to prefer taller guys, and not infrequently, much taller ones (at least 6" difference). Yet I believe it would look "better to the eye" dating a guy around your height, like 1 inch more or 1 inch less.Here are the reasons why:
(In alphabetical order)
1) Less jealousy from her friends
Apparently, a tall boyfriend might trigger more jealously. Sure it's not always that way and it doesn't always happen, but as I said "it's more likely to happen though".
2) More sexual positions
There are some sexual positions, that huge height difference obviously makes it more difficult. So being equal means there are more options available.
3) No excuse to ask for his help in order to reach something
Well, this is a benefit for the guys mostly, not for the girls. But still I believe it gives the impression that girls are being lazy, and want a guy's help in order to reach a certain item placed high. Well stools and chairs exist for a reason.
4) No need for heels in order to kiss each other
Some couples, in order to make up for the height difference, woman is supposed to wear heels wherever their go, so she can reach the man in order to kiss him. And I mean heels at least 4" length.
5) Not awkward in the eye
Well to me such a height difference, like the one in the picture, looks pretty awkward. Still I can't believe there are actually many women who enjoy being so much dwarfed. I can't explain why though. If one of you happen to read this, tell me why you like it.
