Hey...
I have that same problem... but I don't like the way it feels in there... a turn off for me. So what I do, when I'm with my boyfriend, and he wants to "watch", I use my toys.. ***** for him is a big turn on. I think guys just like to watch a girl get off by themselfs.
And when I'm alone, I don't use my hands at all, just my toy. I found it works great,, and have no problem with it

I have found the ones that vibrate are much better

Sorry if this did'nt do much help... i saw the topic and thought I would put my 2 cents in

good luck!!
