What are some things that can turn a girl on?

Little things, mostly soft touching. If you watching a movie run your fingers lightly up her arm, or caress her hand. Really light touching does the trick for me, every girl is different though.

Idk, for me, its really hot for me to know I'm pleasing my guy. Hearing them breath heavily or even soft moans. That like turns me on a lot!
and stuff for me. The neck is a great spot, and feeling up my back or leg while making out. Little subtle things that makes me wonder what will happen next.

Sensuality is a big turn on for me. I love it when a guy softly touches me. Caresses my face. I had a guy trace my eyelid and contour of my face the other night. I thought that was really sweet therefore it really turned me on.

If you think she is comfortable with her stomach. Gently rub it with the tips of your fingers up to her abs and back down. Kiss her softly and gently kiss her neck.

Don't be forceful. She will go crazy!

Sensual music, candles and you can even make her dinner. Whatever can get the 5 senses engaged, works.

Every girls different but sometimes, playful kissing and touching works, kissing on the neck if you do it right can work very well.

well i think you should look at your self first. how do you dress, are you clean, how do you smell. you also want to be able to talk to her about things she likes. show her that you like the same things. let her know how you feel by your actions and body language. don't try to hard to turn her on because you just might turn her off. hope this helps.
