Look for an experienced lass with good feedback which will reduce chances of a bad punt. Check she offers the services you seek and charges rates you are ok with. Check what type of lass you want - older/younger, slim/curvy etc. Check the location suits your needs.
Your size should not matter to a good service provider. Just make sure you turn up clean, be respectful and pay her the cash once you are satisfied the lass is who you booked.
Research - look on AW and make a note of her AW number. Enter this in the search box in the top right of this screen. This will return all reviews and discussions on the lass.
If in doubt, ask again in here.
When you have met her, write a review
