I brought one home a number of years ago to see if my wife could have vaginal orgasms with it. Up until then she did not seem to respond much to vaginal stimulation. She has always been fairly inhibited in the bedroom type situation. Up until that time I think she had only 1 mixed orgasm (clitoral and vaginal both the stimulations were with my finger). With the rabbit she has started having lots of mixed orgasms, never just from vaginal stimulation though. Sometimes she likes just the ears used alone. With the rabbit multiple orgasms have gotten to be very common, it is hard to count them but 4 to 8 are my best guess. I do not know if she ever uses it by herself or not, I bring it to bed because her being excited excites me.
Actually during one of her orgasms when we had new batteries and the inside squirmy going full blast her orgasm was so violent that she stripped all the gears inside the rabbit and we had to replace it.
We have been married over 30 years.
