While I would think that an open forum query isnt the best way to find out, I do think it's admirable that you aren't using the all-too-popular method of finding out a lady's proclivities known as "Fuck asking."
You know...it usually involves that particularly sexy move where a rough, unlubed finger is jammed into an unsuspecting lady's backside without warning or patience...just to see if she's "into it". 😳
