[16M] Need advice on finding a sexual relationship

Ok so this is gonna be wierd to type and im on mobile so: im a 16 yr old virgin with average people skills. i go to a private school that is fairly uptight and have known mostly everyone since I was in preschool so it is really wierd and not possible to start a relationship there. i don't do many outside of school activities that would allow me to meet more people. My last girlfriend was from my school and it was just super awkward and didn't work out. what activities and stuff would allow me to meet people who would be better relationship material?
