These woman are 9 times out of 10 nervous and hiding it though chatter, a point also strengthed by the fact they turn the conversation back to plantonic shit because of self esteem issues talking sexual.

You should be controlling the pase anyway don't let them rabbit on, slow your speech down slightly more than normal don't play catch up, if she's racing ahead and asking you a dozen questions answer one. She's nervous because she's not comfortable, build more comfort, make her feel a bit more at ease.

You talk too much is good but is wrong for a girl like this, it works best on a 10 that needs bringing down a few pegs on a nervous out of control chatty girl it just makes her more conscioius she is nervous.
