New member to both TER and to P411. Can anyone tell me how accurate are the tags the section labeled activities enjoyed in private, in the girls profiles?

YMMV.

not things you're going to get. Read her reviews to get a better idea what you can expect but remember there is no check list and no guarantee. If you choose wisely you'll have a good time. You are already off to a good start finding TER and joining P411. Have fun, there are a lot of good times to be had.

Not that I completely disagree with my fine fellow hobbyist above but the ball really is in your court.  Generally ladies won't put an activity in their list unless they are willing to do them with a high percentage of their clients.  If they didn't they'd probably get a lot of annoyed men bitching about it.  If you are respectful, well groomed, not excessively rough (unless that's the way they roll), and most importantly clean all those listed activities should be available to you.  If you make any type of positive impression over time additional items may very well be added to that list.  That's when things really get interesting.  

...her TER reviews and I've not found an inconsistency yet.

Plus P411 expects the people on their site to meet certain standards of behavior.  An escort who got a lot of complaints about saying one thing on her profile and doing another might get kicked off.

...monsieur le marquis?

Thank you, was not aware of that. Good to know.

It suits me well.
