Get her naked. Do kinky stuff. Put penis in. Take penis out. Repeat steps 3 and 4 until you are ready for step 6. Orgasm. Continue steps 3 and 4 until wife reaches step 6. All done (for now).
Some say size doesn't matter, but it really helps. The best thing to do in bed is be creative. There are tons of different positions you can do. Just make sure she is wet befor you put anything...
