Well since I am 6' 2" I don't think you are to tall and you are very pretty so even if you were too tall I could make an exception.And you have a nice body!If I like a girl then I will overlook pretty much anything.Maybe most guys feel if you are taller then them you will look funny together.There is plenty of tall guys out there just go for the taller ones.You will probably want to be with a bigger and tall guy anyways.Go for guys that are on the basketball team.I think on average girls are 5'2"-5'6" so really I don't consider you too much taller and you are definitely not too tall.To tall to me would be 6' + and closer to 6' 4" would be too tall.Besides tall girls have sexy long legs and that is very hot!You wouldn't want a short guy would you?
Most guys (and girls I guess) think the guy should ideally be taller than the girl - my ex was actually a few inches shorter than me - to her relief - but she would never wear heels in front of me for that exact reason. If a guy is so shallow that he can't date a girl that's a bit taller than him, he's not worth your time. Cliché, I know.
Anyway I don't think you're too tall and I wouldn't care too much if my girlfriend was taller than me, as long as she had a great personality.
