How does an average looking guy compete in college for sexual/romantic relationships?

I have trouble attracting women at college and when going around it's obvious that 10 percent of college men are having sex with all the women. I'm not ugly, I'm average looking in the face and semi muscular due to working out 4 times a week. What advice do you give? Should I look off campus for sex/relationships?(also don't just message some nonsense like "just work on yourself" or "you don't need to be interested in girls right now anyway", it isn't what I'm asking, and it's useless to me)
