Have you or a SP ever said "I love you" during a GFE session? It wouldn't feel natural if you told her to say that so its YMMV.
I can't recall an SP ever saying it but I have heard it from 3 or 4 different dancers over the years, The first time, I can't explain how good it made me feel. That dancer meant a lot to me and her saying that meant so much to me... (I posted about it years ago -- and even copied the post over to my blog. It's the one titled A Strip Club Serenade for anyone who might be interested.)
The second time I heard it from a dancer, I didn't know what to think. Hard to explain the dynamic she and I had at the time. I've thought about posting something about this one at one time but I've never been able to think straight when it came to her. I'll try to make a long convoluted story short. Basically after my all time favorite VIP dancer moved on, I chose a dancer who I knew was an "all about the cash" type. Someone for whom I figured there was no way I was going to develop any sort of emotional entanglement. I had had enough of that sort of thing and I just wanted to be able to enjoy the physical aspect of things without the emotionally confusing side. And it worked for a while and I started to spend a fair amount of time with her and most of the time she'd be "on" and "in character". But you spend that much time with someone and every once in a while she'd let her guard down (or if she was playing the game, go into another "character" -- the truth is looking back, I can't even be sure anymore... I guess I never really was...) and in one particularly unguarded moment, as a response to some off the cuff joke I made, she said it. After that, she'd say it often in parting. One day, I finally broke and said it back to her. Within a week, she straight up tried to play me and everything between us went to shit (I also cryptically referenced this whole thing in a thread years ago. It too is one of my blog posts. Titled, "Is it foolish to utter the love word in the pooning world?" Again, if anyone is interested.)
There have been two more dancers that I can remember saying it but dancer #2 whom I wrote about above broke me when it comes to hearing it (or fixed me, depending on your POV, I guess) that, to me, it has become just another meaningless thing a dancer will say and I just react pretty much blankly to. Hell, the last one who said it to me was someone I'd known for years and with whom I had honestly had a GREAT rapport. I must have stared at her so blankly, she felt the need to repeat it as though she believed I didn't hear it the first time. I imagine that if she had said it years earlier, it probably would've meant a lot to me then as well. But now... I'm just not that guy anymore.
