Like many others, decent FK gets me going.
I have fairly high standards, but in my experience, a lot of escorts offer a bit of FK that is not much more than a tongue flick but not many escorts offer DFK.
I don’t think it’s fluffy to say you can’t expect a prossy to kiss every punter regardless of their breath, etc.
I think if you are clean and fresh and don’t stink they should provide the service, but regardless of hygiene some may not find some punters attractive enough to provide what is still regarded as a particularly intimate service.
No-one is saying they should do services they don't want to do. The trouble is a lot of WGs claim to do FK without any intention of providing it.
Experienced punters realise "at discretion" is often bollocks and will either avoid or ask the question and judge if she's lying, but there are a lot of less hardened punters who are fooled into thinking that as long as they turn up with fresh breath, they will get it.
If WGs only do FK with clients who they find fairly attractive, then they aren't going to do it with a lot of punters so shouldn't have it on the list, let alone in their profile text - even "at discretion". It's just misleading.
