Bit of a stupid question

This sounds so desperate, but I go to an all girls school, and am constantly surrounded by girls, and don't go to many parties and really don't have any ways to meet guys, but I just feel so lonely all the time, and j don't know how to go out and meet guys. I'm not very pretty and quite chubby so it's not like guys ever just come up to me out of the blue. ( also, pls don't just tell me to love myself, that was not self hate or digging for reassurance, I am very happy with who I am, but also honest)
