For me the biggest turn on is when a guy and I are standing(waiting in line/with friend etc) and he gentley pushes his face into the side of my neck. Not extremely sexual but cute. Also when a guy and I are making out I find alot of guys handle my chest a little to hard. Be gentle they do have feeling in them! Carassing the inner thigh, lower back, or the part of the stomach just below the belly bottom is a real turn on.
Now for the more sexual part, alot of guy have no idea how to finger a girl properly. Now it varies from girl to girl but I find its best when a guy uses two fingers and does a "come hither motion" with the both of them, and fast but not deep. Its amazing! When is missionary grind your pubic bone against a girls clit it will feel good for you and her. Also (missionaries my fav
) Thrust your hips upwards and hit the special spot once and a while and it will send shivers down any girls spine!
