Two of the letters about solo Tantra were from women, and both asked about vibrators. I think I could have done a better, more complete job of answering them (sorry!), so I’ve rewritten and expanded on my answer for posting here:
I'm considered something of a radical pro-vibrator heretic in some circles because I refuse to condemn the use of vibrators during Tantric sex. However, I do agree that it's a good idea for women to be cautious about using a vibrator during solo sex more than absolutely necessary, in part because a vibrator can get us used to reaching orgasm very quickly, a tempo that sex with a partner can't match.
Even if you have never managed to give yourself an orgasm manually, I urge you to give it a try and go as slowly as you can for as long as you can. Your goal should be to s-t-r-e-t-c-h out the arousal phase as long as possible.
