Stop! If you aren't erect you go back and find a good picture and give it the full five minutes before resigning to this test.
Once you have your time, mark it down next to "tits" as a category, we will review this data later.
Next category will be "ass", again, 5 minutes max and mark your time once you get your boner - please wait till you are completely soft prior to moving forward - note, there won't be as much nudity this section but if you are attracted to the female form you shouldn't have any trouble getting it up for these beauties!
