Dating Advice for a new guy (if any women read this your more than welcome to comment)?

Ok let me make this simple as possible im 20 years old and just got out of a realtionship i was in since i was 16, it was serious and i was very unsocial for awhile due to it being going back and forth between leaving down the street and 4 states away, anyways im ready to start dating agian but im having issues, im 6,1 black hair and light copperish brown eyes (i know thats not incredibly tall but where im at its taller than alot) and to top it off im broad shouldered and am gettin into weight lifting and running, i know that sounds like i wouldnt have trouble but it seems like its a little intimidateing to the girls i try to talk to and even the ones that pass me by im, but also im not to stylish and im shy it seriously sucks, and live in the middle of nowhere, so i guess what im looking for is advice im trying to get back out there but im tired of being intimidating i know this is probally one of the weirdest questions youll find on here but im ready to turn my life around any advice be much appreciated , so the key advice i really want is how to be less intimidating, more stylish, some approaches or conversation topics that'll might work, and any inspirational advice to help get over my shy side, maybe a few good ideas for first dates or things to win someones heart, please dont get the wrong impression im not looking to get a ton of girls for contacts for a fun time or anything im really a one girl kinda guy i just need help finding one, im open for anyones advice just really looking for some from the more expirenced people but ill appreciate anyting.
