A nice vibrator is an essential instrument.
But forget the battery-operated phallic imitations, because these things are unreliable and the noise they make even frightens the neighbours.
Go for a proper AC mains powered massager. They are silent and reliable, and come with a range of attachments for use on various parts of the body.
Warning:- AC mains powered vibrators are very safe in your bedroom, but must never be taken into a bathroom or any area where there is any risk of the device falling into water or getting water in it.
My favourite for gyno examinations is a small 'L' shaped Breville Soothing Massager model P33, and included in the kit is a knob shaped attachment that Breville can only describe as a "Special Attachment". And by that I know they mean "Clitoral Stimulator"!
Even ladies who have been inorgasmic (unable to come) their whole lives will find 100% benefit from the use of this instrument in your gentle hands.
I recommend massaging the vaginal area with this sort of vibrator before inserting the speculum. Apply a small amount of water-based lube so the knob of the vibrator slides easily up and down and all around the sensitive folds. Take your time and talk gently with your patient to determine the area that she likes stimulated. Using the switch on the vibrator handle, vary between high and low vibration settings occasionally to determine the setting she prefers. As she becomes aroused and approaches orgasm her preferences will change, probably to low vibrations either side of her clitoris. Don't rush this procedure, she may orgasm if she wants to, and there are multiple orgasms ahead.
You can pass the vibrator to your patient so she can explore herself with it while you prepare the speculum for insertion.
Once the speculum is inserted and adjusted with her cervix centred nicely, she can continue to stimulate herself, or you can take control of the vibrator and continue the treatment. But don't let the vibrator touch the speculum because it makes a loud noise.
What you will see inside her vagina when she starts cumming is better than sex! It's a glorious internal view of her orgasms actually taking place.
I just love this sort of play. And every time I see it I am overwhelmed by her beauty, and I consider myself a very lucky guy to have her share her body with me this way.
Brachio.
