For my self, once a "connection" has been made, I would be more than willing and able to explore new terrortires. But I have to say that rough(er) sex wouldn't be on the menu for a new comer.
A little hair pulling, spank or nibbling never hurt in the heat of passion, but trust and respect also has to be in the factor to enjoy it.
Like many others have stated... it never hurts to ask what the ladies limits are if this is something your looking for, because obviously many of you could be getting this type of serivce from many women.
