I hardly use Agencies, so cannot answer your specific query.
Usually, it is worth asking, but quite often you may get a reply that it is up to the girl, which does not help a punter when selecting a girl.
Alternatively, enquire with other punters which girls provide what services. PNet has fair bit of info on VIP and Feline, as their threads have been going on for a while.
If members add here what services were offered by VIP or Feline girls, then this thread could become a reference point for Agencies in Nottm.
