For a long time I thought a Hitachi Magic Wand would make an incredible G-spot vibrator, but I also thought most younger women couldn't handle something that wide. I searched on the Internet from time to time, and I eventually found a Hitachi-like vibrator with a narrower head. (I don't have a link to it at hand, but I'll search for it if you send me a note.) The brand I found makes 3 of them -- one that plugs in, one that has a rechargeable battery included, and one in which you just put a 9-volt battery. Your choice. I bought the one that plugs in. The head is only about half as wide, and it has a similarly smaller body.
I've only tried to use it once (a real dry spell here in NYC for some time :-( ). In that case, a young college coed asked me for help, since she was having trouble with orgasms. I got her very excited with electro-sex, and started to insert the mini-Hitachi-like vibe. I never got to see if it would work really well on her G-spot because, immediately putting the head (enclosed in a condom) just in the very opening of her vagina, she had a huge orgasm, including thrashing about, and that ended our session.
I have never had another chance yet to try this again, but I'd like to.
I have been hoping that another woman I met some years ago would turn up to try this vibrator. She's a nurse, but the most amazing thing about her is that the front edge of her G-spot is right at the opening to her vagina. Not an inch or two inside. She has incredible orgasms as a result. I've been wondering how this Hitachi would work on her, but she left the area a few years ago, and I haven't heard from her since. She told me that she was really wild as a young teenager. My theory is that the forward location of her G-spot has caused her to be extremely sensitive and orgasmic from her earliest years.
If I ever get to try this again, I'll let you all know. Anyone need a therapist?
