for women, decent non stuck-up women, looks take a back seat to personality. Its all about how you carry yourself. And have a sense of humor too, be able to laugh at yourself and her. Do that and you'll see women will describe you as attractive.
NOW, if you are speaking in terms of just looks? Umm, do you have a sister or something around your age? If she has friends, ask her to ask them what they think about you. I have hung out with my sisters friends (im 24, theyre 21 - 22), not trying to get with them though lol, and afterwards when we'd have a good time, my sister would tell me, "oh, so and so thinks youre sexy." Gives you an idea, and a confidence boost, but dont let it go to your head. Sometimes Id get negative answers too. Being attractive is subjective, some will think you are, others wont.
It also helps to have standards. Dont tend to a womans every whim in the hopes of having sex with her. She'll know what you're trying to do. Have things that you believe in, things you won't do no matter what. Often on first dates, when everything is playful and we get back to either her place or mine, if the convo goes towards flirty and sexual, I'll tell her honestly, and say "We'll hang out for a while, but dont get any ideas!, I don't do anything on a first date." Often I've gotten the response, "really?" And ill tell them "nope, there's nothing you can do that'll make me get undressed yet." - At this point, some of them actually start trying to think of things to do to try to get my clothes off. They like the game/challenge.
Thats just a goofy example, and its fun!
