Now hopefully the vagina that you're dealing with is well lubricated, but that won't necessarily be the case. If you spend a long time at this even the juiciest woman can start to dry out, so it never hurts to have a little lubricant handy, just in case. I'd recommend K-Y jelly, which you should be able to find at any pharmacy, but there are lots of alternatives. One that I wouldn't recommend is Vaseline - too thick. Another is baby oil, it's too thin.

You can entertain yourself by running your finger around the inside of the vagina, trying to discern its shape. Unless your female is coming (having an orgasm), you should probably find that the vagina is reasonably form-fitting, although some are tighter than others. If your female is not coming or consciously causing contractions you'll probably find that the vagina isn't doing anything in particular, just sitting there and producing lubricant. If you bring your finger to the front wall of the vagina then you'll find it less yielding than the rest, because there is a bone in front of it called the pubic bone, part of the pelvis. If you feel along this unyielding section or just beyond you may find a slightly raised area. This is the G spot. It might not be raised, but it will engorge once your female starts to come.

Don't poke this spot yet. Don't do anything with it, yet. At best you won't have any effect, and at worst you'll be distracting. You've got to wait for your female to start to come. Now this might happen in thirty seconds, or it might take an hour, and you've just got to be patient and keep things regular and smooth.
