Has my frequent vibrator use possibly desensitized my clit? And
therefore will my ability to orgasm be suppressed? If so, then should I talk to
my partner about it or just stop flying solo (with my toys) for a while?

Excellent question!  This is an extremely frequent concern among
vibrator connoisseurs everywhere.  The
simple answer is no, frequent use of a vibrator will not desensitize a
clitoris.  There is nothing about the
vibration stimulation that damages, reduces, or changes the physiology of nerve
receptors in any way.  Orgasming from a
vibrator, no matter how many times you’ve done it, will not interfere with your
body’s capability to orgasm in other settings.

However, it is possible
to become accustomed to a certain types
of stimulation.  When we train ourselves
to orgasm a certain way–whether it be the toy we like to use, the jerking
motion we’re a fan of, the tongue lapping we frequently request, the rubbing
technique we find ourselves coming back to time and time again, whatever — it can
be difficult to imagine ever being able to come a different way ever
again.  This is rarely ever actually the
case, as the brain can be trained to incorporate many different types of
stimulation into its repertoire of reward indicators.

If you’re fretting at
the possibility that you have become accustomed to getting off with your vibe, I
have a few suggestions.  You could try
laying off the toys for a bit, although it’s totally not physically necessary.  If you want to get yourself real riled up and
horny, abstaining from masturbation for a couple days before hooking up could
do the trick.  You could try using your
vibrator in a different way or even experiment with a different toy that will
do the same trick.  You could suggest the
possibility of inviting your best friend along for the bedroom party with your
partner, as long as you talk it over beforehand — toys need not be reserved
solely for solo play!  If your partner
feels concerned or threatened by the presence of the toy, you can try
reassuring them that your advanced homeosapien brain recognizes that human
connection trumps any kind of pleasure that an inanimate object can provide you
with.

Lastly, if you’re
interested in mixing the strength of vibration with the human skin-to-skin
contact with your boyfriend, try this neat trick:  Take a small bullet, egg, or peanut vibrator
(as little as $5 at sexuality boutiques or online sex toy shops).  Turn it on and place it in between your index
finger and thumb, with your index finger slightly extended beyond the bullet.  Voila!  You have an instant finger vibe!

Hope that helps!
