Does Having an Average Face and a Good Body Affect Dating Opportunities?

I'm a 25-year-old woman, and I feel like I struggle in dating because I have an average face but a good body. Most of the men I meet seem to be interested in me only for casual sex, which makes me feel like I'm not pretty enough. Also is the idea of 'dating out of our league' really a thing? I sometimes wonder if that's what's happening to me. It’s tough feeling like I’m not good enough because I don't have standout facial features and I am mainly desired for my body.
