Compliments can backlash.
I remember the first time my wife said "I'll give you five stars for that one"
That's now evolved into her giving me a rating, up to 5 stars each time we fuck. If she forgets to rate me, I can barely last 15 minutes before I just can't stand to not know and I have to ask.
Thing is - she's cunningly turned it into a competitive endeavor for me. I now no longer find myself getting lost in the love making or focusing on enjoying it, nope - I'm just pushing for that extra star.
She's very clever, I'll give her that. I'm usually good for 4 or 5 stars - even I can tell the difference between a 4 & a 5 start fuck. I occasionally get a 3 when my hearts really not in it.
I'm not sure how I'd handle a 2 star rating....
So anyway - be careful of those compliments. Next time she'll be telling you she lost count at 5 orgasms and you'll end up in the same boat as me.
