Besides Doggy Style, Comissionary and riding, name a fun, exciting sexual position? have you tried it?
(Pictures Are Welcome...LOL)

Dancer. Lady places leg over top of mans shoulder. I dont think I need to say the rest. :)

Wikipedia has a long illustrated, alphabetical and categorised list here.. http://en.wikipedia.org/wiki/Sex_positions

Personally, I like the Spoons position where the female lies on her side with the bottom leg straight and the top leg bent. The man moulds to her back and also bends his top leg to fit into hers - alternatively he can put it out straighter and she can clutch it with her top leg. This way there is room for him to manually stimulate her clitoris, whilst allowing for deep penetration and 'jack-humping' without the knees and hips getting sore as they do in Doggy style.

I believe that the comissionary position is only reserved for hookers. Unless you also make commission on a position.

Man kneels sitting on his heels with woman on her back legs round his waist.ass on his lap. Good for anal too.Means clit available to stimulate or pussy during anal.Woman can sit up to alter angle.

The man entering the woman as he holds her in front of him either with her back against the wall or without the wall. Deep penetration!

Did you mean "missionary?"

well theres:

rape, Forced rough sex...

fisting (Stuffing your hand or foot in a womans vagina to open it up...)

Animals (Beastiality)

etc...

Manchurian Rape. Sorry I don't have any pictures and a word picture just doesn't do justice.

Reverse cowgirl always does it for me....seeing her bounce and my dick go in and out of her with her moaning on every entry makes me cum fast as hell everytime, I love it.
