I've always had problems with vibrations not arousing me, rather they usually make me itch like crazy or numb me out immediately.
I can always come in about a minute & a half just by touching my clit, but I don't usually want to come so fast & I still felt like I was missing something. Once I found a dildo that was comfortable, the fullness solved the missing something problem, even without thrusting it.
Thank heavens for the return policy here, or I would never have bothered to experiment & find out that there are some vibes that DO work for me after all. And when you combine all the variables together...well, now I get it!
