Ways to move during intercourse:
Short thrusts
The penis doesn’t go all the way in, but glides back and forth in the first 2 inches of the vagina. It requires some practice to keep the penis in, not letting it slip out. For girls this can be a exciting technique in sex positions in which the G-spot is stimulated, like doggie style and spoons.

Long, deep thrusts
You enter the vagina till you cannot go any further and then draw back, stopping just before your penis slips out. Then you go in again. Many guys prefer these long movements because their glans is stimulated over the entire length of the vagina. This technique is no good for guys who come (too) quickly.

Short, deep thrusts
The penis remains deep in the vagina and the movement is small, not more than on or two inches. For the guy this is less exciting, but for the girl this can be very exciting if his pelvic bone touches her clitoris (indirectly). This effect is even stronger with a circular motion. It’s a good technique if the guy has difficulty controlling his orgasm or if he is close to the point of no return and wants to postpone orgasm.

Circular motion
Instead of thrusting the penis goes as deep into the vagina as possible. The guy or the girl then makes a circular motion, his pelvic bone stimulating the clitoris.
