If you stick to one ML then she will expect you to see her regularly. Sometimes they get lazy and will just talk to you instead of massaging and talking at the same time. We know women can do this better than men. It's nice to chat with them but not when time is ticking and you're paying for it.

It is a good idea to probably have a favourite ML that is reliable and will be available for you. At the same time, you're not married to a ML or signed a contract with them. Therefore, see other MLs. There are many out there and please be respectful.
