Can I get a guy's opinion?

I feel extremely stupid for taking my insecurities here, but I want outside opinions.I constantly get compliments from GIRLS, but never guys. It's a rare thing if I do. I'll attach a picture down at the bottom for looks. I'm thinner and short ((5'3.5")) I've been told that I look approachable by several people, but I've also been told that I look like both a b*tch and a slut. I don't dress in ways that suggest I am. Shorter shorts during the summer, but nothing too short. I do believe I'm a pretty interesting person once you get to know me, although I've been compared to Effy Stonem from Skins on occasion. I'm pretty smart, I think I'm relatively funny but I'm not super outgoing. I think I walk a bit insecurely, but I've been told otherwise ((like I'm overly confident and won't give a guy the time of day)). I don't believe I dress terribly either. My style is also something I get constantly complimented on - also by girls. My group of friends is all girls with the occasional few guys that will come say hi and stay for a minute. Some of my guy friends like to tease me and pretend ((I hope)) and call me a lesbian. My question is, why don't boys seem interested in me? Is it my looks? Attitude?

Sorry it's long, but thanks in advance.

Sorry, none of these pictures have filters on them.
