First, I get tired if the provider has a 7 in the looks department, and I'll probably won't go back. However, I'll go back again if she has spectacular skills. I hate to break the news to you, but, it's also the same for very attractive providers, ranging from 9-10's on appearance. Met this one chick that was consistent with 9 on looks and 10 on performance. Seen her like 5 times, and got tired. Same with others, after seeing them so many times, you been there, done that. What's new?
I have learned that, waiting for a month will defintiely increase your drive. I was seeing her like 5 times a month, that's overindulgence. It's like having an SO, you get tired after a while, and want to fuck something different.
To answer your question, yes, it does happen to the majority of hobbyist. Now, if I have a favorite, I will only see her twice a month, or just once a month. I find that changing my diet, which means, seeing multiple different providers definitely increase your sex drive. Also, try different varieties too. Don't just stick to blondes eye spinners, mix it up. Last month, I mainly saw mostly puerto rican girls, and damn, my sex drive kicked into overdrive. They can suck a good one! Had this one puerto rican girl, she sucked my cock so good, I booked another appointment with her the next day just for the cock sucking session, and didn't want the pussy.
Anyways, mix up your variety, and limit the amount of times you see her.
