Men and vibrators have a very turbulent relationship - but only when they're kept apart. For that reason I issue a standard piece of advice to gals whose lovers feel threatened by battery-operated love machines: arrange for the two to meet. Let them become friends. Allow the vibrator lose its mystique by turning it from a girl thing into a couple thing. I suggest this is where you went wrong in your previous relationship - it sounds like you never brought your vibrator out of the realm of 'hypothetical and therefore intimidating' into the world of 'real and therefore approachable'. You allowed your ex-lover's fear to ferment and expand. So please don't repeat this mistake. Bring your buzzer with you into the bedroom, and once it's there, never EVER favour machine over man. Let the vibrator do the early donkeywork (as it were) but give your boyfriend the privilege of finishing off the job. Moreover, let HIM manoeuvre the machine. This has the advantage of putting him under the impression that its his nifty handling what's making you writhe and moan rather than the 10,000 vibrations per second pulsating from his palms. So you see, getting your lover to accept your vibrator is all about skilful handling - of the bloke even more than the silicone device.
