it's just mainly a problem for me because of the type of man I'm looking for.

but nerdy guys like attractive girls too... attractive girls are appealing to everyone.

with that aside, i THINK i understand how you're feeling. sometimes guys who are way different from me like me and i like them back but i'm hesitant to enter into a relationship with them because we're so mismatched, and this feels so constraining and limiting and frustrating. it's like we wouldn't conform to society's expectations and people would wonder what we were doing together. for example, i'm very short and i love both short guys and tall guys, but whenever an especially tall guy shows interest in me, i feel sad because i know we're "mismatched". people would stare at us. we would never be one of those couples who "looks good together". i'm not trying to say tall guys are better than short guys, i'm just trying to demonstrate how constraining it feels to have your dating pool limited based on how good you two would look together, even though it shouldn't be a concern. this isn't just something i personally feel, it's something the people around you are also aware of.
