I think it works pretty well for this purpose. I use it simultaneously with a dildo all the time. Is it the best for this purpose? I would say you'd be better off using a smaller vibrator such as the Lelo Siri which is another personal favorite of mine during piv sex. Although it is pretty easy to use the Gigi. Works in all positions where your body isn't completely pressed against a surface or your partner's body. You'll need to give a little space in between you and your partner to fit the toy but it still works really well. less
