There are a few ways to use the Pulse II. One is for the dude to lube up his penis and put his shaft into it and basically jack off; which seemed to fairly amuse my guy, though he said he preferred his hand over the toy. The way to use it as a couple, though, is basically to dry hump while his shaft is inside it, with the woman rubbing up onto the hard, vibrating side of it.
Having a vibrator you can use during sex is a great trick to have up your sleeve: not only does it make orgasming during intercourse a lot easier on nights when you need extra help, but it also feels great for the dude you might be worried about freaking out. Here's why: You're even tighter down there while using a toy (because you're so turned on) and your vag itself is lightly vibrating, meaning he gets to contact a great second-hand high. Instead of worrying about what guys might think about using a sex toy in bed, we should probably be more concerned about them becoming even more addicted to having sex with us. (Seriously. It will probably blow his mind a little, in my experience.) Sex Toys
