The stimulus of a vibrator feels good and a vibrator never gets tired.
Some women can only orgasm with their vibrator (for argument's sake).
A woman may discover other modes of having an orgasm like multiple orgasms on the clit, in the g-spot or during penetration with a little bit of practice.
Experimentation is vital (A woman needs to know her body for a man to give her an intense orgasm, too).
Vibrators may work on those occurrences when an orgasm becomes difficult.
Vibrators are great for "quickies" and batteries are cheap.
A woman doesn't have to be nice to her vibrator in order to receive satisfaction.
A vibrator will not orgasm first and fall asleep.
A vibrator brings novelty into the bedroom.
A vibrator feels good to a man who may also want to watch.
There are many varieties of vibrators for all seasons and for different kinds of pleasure zones in the female anatomy.
Vibrators will never give a woman a disease, a one-night stand or get her pregnant.

It's not a cock.

The best IOI I ever got was: "I'm tired of using my vibrator..."

I am actually surprised we have not seen a thread "When a girl says "I'm tired of using my vibrator!", is it an IOI?


Peace...

There are different ways you can have an orgasm, you can have a clit orgasm, or you can have a vaginal orgasm, you can also cum with the ass, then you have more pleasure in the ass and you cum lighter in the pussy. So even if vibrators gave women guaranteed orgasms, they would only be superficial and not at all satisfying.
In the beginning, you're pretty much guaranteed an orgasm, but then it numbs the nerve endings in your clit so that the 10th time you use it you'll have a really hard time getting an orgasm. In the end, you end up with one of those Hitachi Magic Wands because it's the only thing that's going to give you enough stimulation to cum. There is no point in buying something that gives you sucky orgasms (a vibrator). You should buy a buttplug instead because then your girlfriend can learn to have anal orgasms, she can learn to enjoy her ass more. It's like you get a completely new sexual experience. It's much more rewarding than any other adult toys
