Am I worth a girl's time? Am I any good?

I'm 19 in first year's college, and I have never in my life dated, or even hung out with a girl before. I always feel like I'm not good enough, and scary. I say scary because I'm kind of buff, and I have scared the **** out of a few girls without me doing anything. For example, once a girl came to ask me a question about our homework. She then said to me, "your eyes make you look like the devil. I don't want to talk to you anymore." I thought to myself, wff? What did I do? I was just looking at her. Also, I was on the bus once, walking to the back. A girl was sitting with her boyfriend having a convo. The whole time I was walking to get to the seat in front of her, she was giving me this dirty look. I didn't stare at her because I'm a little shy, but I glanced here and there, and that's how I noticed she was giving me that dirty look. When I was at my seat, I glanced at her and stared, and she literally opened her eyes really wide, and jumped a bit like she was about to have a heart attack. Her face then turned red, and she looked away. I know I'm not cute, but people have told me that I'm very handsome. I really don't see it, and sorry I don't exactly want to post a picture of myself. I'm 5 foot 7, buff, and presumably "handsome." I also play the electric guitar, and am working on becoming a film editor/director as I am in a 4 years bachelor of arts university degree. I make many short films. Every single one of my friends say I'm like the funniest guy on the face of the earth. They also say I'm very honest, polite, a little too generous, very truthful (I stick to my promises) and very fun to hang out with. I also enjoy having conversations about ANYTHING. All my friends seem to come to me first with their problems because they say I'm very helpful, and knowledgeable about solving problems. If all this is true, then why can't I get myself a girlfriend? Am I scary (based on my 5 foot 7, and buff description)? Is what I'm doing worth a girl's time? I'm 19, and I feel pathetic even asking these questions on this site. What's wrong with me? I forgot to mention that because of the way I was raised, I have never said the words "I love you" to anyone, including my own parents. Also, I have never hugged anyone in my life. I really want to learn how to, and I was hoping a special girl can show me how. Is that a turn off?
