I'm nearly 18 and 5'10, I'm really self conscious as I feel that I'm not very tall and I always see posts on social media about how girls adore tall guys
I'm the same height and I'm a girl but I'm pretty tall for a girl. I don't really see guys that height as 'short' tbh, I see 5'8 and below as short. Maybe 5'9. Most girls are shorter than you so don't worry you will be fine If a girl doesn't want you over something superficial like your height then it's her loss anyway.
That's the UK average so....it's not exactly short. I'd consider 6ft plus to be tall, but my boyfriend is 5' 10" and he's a good height for me (I'm just under 5 foot 8.)
I have seen plenty of guys at your height with hot girls. If you're confident and consider yourself to be someone of high value, with whatever you want to achieve if you want it bad enough, you will get it.
