How well do you know your vagina?

I don't understand why you wouldn't want to get to know it. In the same vein that you know which kind of body shape you are, where you are likely to get wrinkles or pimples, what makes you sneeze, what size jeans you are. Your vagina is such a critical part of you, and learning something about it (unlike learning your waist size) will result in lots of pleasure for you. Surely that should be incentive enough to get acquainted?
Hopefully you've had a little read about 'the claw' already. The claw works so well because it is hitting those good spots in the vagina that are common to us all. Clitoris /bladder muscle/g-spot/entrance. Having a little play with the technique yourself (rather than having a partner do it) and not sticking necessarily to my 'plan' or 'rules' also helps you get to know the ..space inside. So set aside a little time, in the shower perhaps, or even on the loo if you can't time on your own in bed... I'd suggest doing it alone first off, so you feel completely comfortable.. then, do it with your partner (see this week's challenge). Get yourself stimulated, and once you've got your two fingers in, start to work out where everything is in there. Explore with your fingers - where are your two pelvic bone cavities (as you go in with the claw, they're on either side of your straight, normal vaginal passage), what happens when you press in those spaces (they don't often get touched unless fingers go specifically looking for them.) What happens when you turn the claw around (so instead of touching against your stomach-side wall, you are touching your ass-side wall) do you feel stimulation there? Have a good feel around, anywhere you can get your fingers into. Don't forget right at the opening, the early-middle passage.. take it slowly feel it all. Inevitably, you will find bits that feel good when they are touched and bits that are just so-so.
Do you have lumps or bumps or even bits of hymen scar tissue anywhere, do they feel good when pressed or tickled?
What about your clitoris? Is it super sensitive, or can it be rubbed raw before it starts to feel good.
Work all of it out. I think you will be surprised at how many hidden passages there are inside, how good certain bits will feel, and how stretchy and large the vaginal 'passage' can seem to get. (More on that last a little later down the track.)
Be gentle when you begin, and as always with anything sex-related, pee afterwards. Always drink loads of water, hydration helps get everything flowing 'down there'.
Have fun with it, it's not a chore!
