First, ask yourself, what kind of guy are you looking for. Get yourself some standards. Do you want an intelligent guy, a strong guy, a suave guy, or any mixture of these traits? There are no wrong answers and it's ok to experiment. Then, ask yourself, what are your strong points? What do you find sexy about yourself? It's important to be confident. If you like a guy, flirt with him, if he responds positively, great, if not, there are plenty of fish in the sea. Don't be afraid of rejection, it happens to the best of us. Attraction is a skill, and as with all skills, it's hard at first and takes constant refining.
Be Yourself! I find nothing more attractive than a girl who is comfortable with being who she is all the time. What I mean is Ill say I like a band or a movie and a girl will tell me they are awful and we will flirt around about our taste in music or movies. She didn't just agree with me when she could have. One day you'll find a guy who will absolutely love you for this and things will just start to happen.
-Always smell good. I noticed that guys seem to like sweet-smelling or floral scents the best. -Make sure your hair is done all the time. Boys love girls with pretty hair. -Smile so you'll be more approachable. -Play up your figure but don't show too much skin either. Nobody likes a slut lol.
