Apparently if he has the time to see 15 girls in one month and spend roughly $1500 each month, then that shows he has a lot of free time and can afford that type of lifestyle. If you gotta work a 9-5, then it would be difficult to see 15 ladies in one month. I use to work a 9-5, and damn, I use to get tired as shit after the day, and not want to do anything.
Atlanta has a lower rate than most cities, which makes it possible for the hobbyist to achieve those numbers. If I lived in Atlanta, I'd see multiple women in one month too.
I wouldn't say they are addicted to buying pussy, it's just a lifestyle that they can afford. If its addiction, then their financials and relationships are affected. Apparently, he is able to afford seeing these girls in one month. Some guys have the energy and luxury to see plenty of girls in one month, while others can't. Not every person is equal.
I don't regret seeing multiple girls in one month. In the past, I use to take an entire month off and devote that entire month to seeing providers. Its a lifestyle choice that person chose to make. You've never live this lifestyle before, so, you have no experience in it. I can tell you that it is enjoyable to see multiple girls in a month, but, after a while, it does get tired.
I've been hobbying now for over a year. At first, it was the rush, excitement of the journey, and the feeling of sleeping with multiple girls. I've had some months where I would see over ten girls in one month. There were a couple of times I took vacations and saw over 15 girls in one month. After a while, it does get tired.
Its not like I can't get free pussy, its just the convenience of it. I have an SO, and I can get sex from her anytime. However, it does get tiresome fucking the same girl over and over again.
So, to answer your question. Some guys are more fortunate than others, they can work less, have more time available, which enables them to see multiple girls in a month. If you can live their lifestyle, I think you would be tempted to try it. From my experience, you will get tired after a year or so of seeing plenty of girls. After I have overindulge in pussy, it all seems to be the same. I've seen all types of girls, affordable to luxurious providers. I am at that point in my hobbying career where seeing only a few providers in one month is more satisfying than seeing 15 or so providers. It's just more satisfying to me. Over indulgence can be a bad thing.
I only saw that many girls in the past because I was still new to hobbying, and everything was still exciting. Now, a few here, and a few there is good for me.
