I agree with the comments about asking the particular SP about this. Especially if this is a must have item for you.
I would say that 98% of the women (SP's and non-SP's) really enjoy DATY done properly.
That said, some may give the impression they don't enjoy it.
I have know some ladies who are very sensitive down there. Unless you are super gentle (this often requires instruction on their part) they actually find DATY uncomfortable. I've seen others, mostly those with an SO, who either don't allow it or offer it reluctantly (save that particular activity for their SO) thus giving the impression they don't enjoy it.
Just like most sexual activities, honest and open lines of communication between you and your partner, will give you the best chance at achieving the satisfaction you both desire.
Cheers
