Use eye contact. Exchanging eye contact and a few stolen glimpses can help send a message without saying a single word. When you caught someone staring at you every now and then and he seem really interesting, build eye contact. Lock eyes for a few second and immediately look down or look away and smile. Most men find women who are willing to exchange glances more approachable. Be careful not to overdo it because he may think that you are too easy.

Avoid going out with a big group of friends or hang out with your guy friends. If you want a guy to approach you, do not make it too hard for him. Be more accessible if you want to be more approachable to guys. Guys will not approach you if you keep hanging out with your guy friends. Being with a big group of friends can be intimidating for any guy to approach you. It is easier if you are alone or with just one girl friend when going out. Of course, you are old enough to know where and when you can spend time alone and get the chance to be approached by guys without jeopardizing your safety. Bookstores, coffee shops are ideal safe places.
