I wouldn't even say to aim low... unless your target is Megan Fox with the body a victoria secret model then yea, you might want to aim lower. But there are a lot of hotties out there and don't just automatically assume they are out of reach. Some of them are way more accepting and friendly than you imagine, you just gotta start bullshiting with them a bit and either you get shot down or you don't, move on, you will land it. There's some real fucking doofy looking dudes with hot chicks and not all of them got it for their money. If you're decent looking or a "pretty boy" it should be no problem. just do it and don't sweat the ones lost.
