I'm 5'9" and 115 and have a few friends who are taller... There are plenty of guys taller than you, and I bet most guys shorter than you wouldn't care too much, especially if you're pretty. Guys still flirt with me and don't seem too intimidated by my height. I think if they were, I don't think they're worth the time.
People tell me I should model quite frequently, and I think my height contributes to that a lot... it can make people look more... elegant? But in any case, if you're confident with your height guys will like it too :)
Guys, especially your age, like girls who are pretty, gorgeous etc. Average height for guys is 5"9, so expect to be taller then at least 60% of the guys you run into. Guys would like to be taller then you, but it's not going to put them off if you're taller then they are.
Agh I'm pretty much the same but weigh 114 I feel like I won't be dating for a while because I'm taller than the majority of guys. I hate being taller than them because I always hear from guys they wanna be talle than the girl because it's pretty much just normal and they like to be the dominant ones
