How do I get a girlfriend?

im 17 and going to be a senior in high school. I have friends but they are all guy friends. I don’t know if you consider girls that you only talk with in school “friends” if they are with there boyfriend when we are hanging out with him, I will talk with them. im the nicest guy you will know. I cant really hold a conversation with them. im not a loser but im not the most popular. im not that attractive tho, im not dorky looking or anything but im not built or have a 6 pack or anything. I hang out with the jocks, even tho im not one, but they are not the “im gonna beat up the nerds” kind of jocks, they are jocks in the sense of playing sports, and thats it. every single one of my friends play sports. im always at the end of the “even so and so cant do it!” joke. but its in good spirit, they dont make fun of me or anything (thats just to better explain me). none of my friends are players or anything, but some of them do have girlfriends. my school only has 500 students,. now its not farmland or anything, its just a small city. I feel like im just ranting now, im sure most of that info wasnt even needed lol. also, im not the party goer type either, not that I get asked to any but if I did, I wouldnt go, my friends dont attend the parties either, well a few do lol. im not anti social because I love to hang out with friends, its just that they are all guys. I just think that girls just see me as the nice kid, not dating material. sorry for this being so long and thank you in advance for reading all of this. please give any info or ask any questions that you have
