F here. Yes, multiple. I have 1 for travel that's discrete, 1 for the shower which is battery operated and 1 Hitachi for if I'm really in the mood to scream haha. I have one for my bum as well which is only used quite rarely. So 4 in total, but only 2 used at least monthly.

I remember expecting like porn-style ropes of semen but it was actually quite showery IRL. Like being splashed by a warm water tap. Also, I was surprised that it doesn't come off hands as easily as I was expecting - it's kinda oily.
