Here are the tips:
1. Look into his eyes and smile on him
When you are chatting, try to look into his eyes and smile on him, then try playing with your hair or stroke your arm or tummy. It will get boy's imagination start going!
2. Dress sexy clothes that show off your body
This doesn't mean you have to dress like a slut! Just simply by wearing short skirts, form fitting shirts, sweaters that accentuate your breasts, daisy dukes, halter crops, tight jeans, and you'll be able to make guys notice you. Remember, unlike females who prefer to leave things to the imagination, guys love visuals, this is a powerful sexual stimulation. Even the guy of your dreams won't be able to stop thinking about you if he spots you in a sexy outfit. It will immediately boost his sexual desire.
3. Touch Him!
Any time and anywhere, you can try to touch him on his hand or his Arm. A good way is to say, "put your hand up and let me see it", and then you put your hand on his and pretend you are seeing the size of your hand to his, then let him see that you like, or at least, don't mind him touching you, this shows trust.
4. Act like a lady.
A lot of guys are really turned off by a woman that comes on strong and trashy. Be yourself! That is the best thing to do. You want a man that is interested in you for you and not because your piece of meat. If he's only interested in you for sex, then he isn't worth having. Please have respect for yourself, and don't do something that you later will regret!
5. Stay simple yet mysterious, be interesting, and not be boring!
Just let him crave for more info about you! Don't tell him everything about you. Develop a good conversation with him every time his around. Don't focus on him, act as if his not there, in that sense he'll be puzzled why aren't you paying much attention on him when everyone else does!
Actually, there are many more tips to turn a guy on, but anyway, I just give you the most tricks that have a high success rate to make a man start getting interested in you. Lastly, I want to remind that you must never obsess with a guy you can never have. There are so many more fish in the sea, so many more guys you can love who actually deserve your love.
Finally, you must remember to not ever hurt yourself for some guy who will never learn to appreciate you or just want only to have sex with you! Just go with your heart, take care of yourself, and let things happen naturally. If it's meant to be, it's meant to be. Good luck for a good sexual relationship, girls!
