What are some?

missionary position is a classic: girl lying on her back, guy above her. this position can be modified with piloows under the girl, the guy getting on his kness or the girl on the bed and the guy kneeling on the floor.

doggie style: the girl on all fours, the man kneeling behind her. Again pillows and changing lying or kneeling positions can be pleasurable.

backwards doggie: the man lying and the women sitting on top while looking away (to his feet)

Different sexual positions are pleasurable to different poeple, you have to be creative and try things. That´s the fun part of discovering your partner and your likes.
