an you talk a TOP only TS provider into being a bottom ? or vice versa ?  
i've never asked a bottom only girl to top because i have assume that a number of bottom girls simply cannot get hard and functional enough to even be versatile and up to the task.  

There's one local girl in my town that does advertise as a Top only but i would love to try to hook up  
with her if i can talkher into bottoming for me.  

There's another provider that i am told by a close friend of hers that she is a top only (although she does NOT advertise as a top only) she is another one that i consider but could be limited
