There are definite benefits to developing a regular relationship with one person such as: getting to know each other's kinks, having a deeper emotional connection, sharing special events together, and enjoying long story arc role plays. But there can be drawbacks as well - such as: it's easy to start crossing personal boundaries, jealousy can enter into the picture, what happens when she retires or goes on long holiday leaving you out in the cold?
I've done a bit of everything in my hobby career over the years from trying to bang every girl in town (heh) to maximize variety and the thrill of the chase to working on one relationship almost exclusively to maximize emotional bonds with a very special person. It's all good - don't let anyone else tell you how you should hobby. It's your time and money - spend it the way you enjoy the most.
What works for me is developing a close, regular relationship with a couple of ladies. I find this maximizes advantages while minimizing disadvantages. Let me explain.
Having a couple of favorite ladies allows you to partake of the advantages of being a "regular" without too much risk of emotional/romantic attachment with one person. It also gives you some variety by not seeing the same woman every time. Who doesn't like a little variety now and then? And if one of your favorites goes to the Bahamas for two weeks, you still have your other to keep you company while she's away. And if - God forbid - one of your favorites retires, you can audition a new replacement fairly easily. Which is a fun process in itself.
Not to mention most ladies require two referrals anyway to see a new client. So why not have a couple of favorites? It actually solves a bunch of problems.
And keep this as a secret between us gents - but sometimes a teeny, itsy bitsy, weensy competitive rivalry between two favorites can keep them at the very top of their game. At least where you are concerned. But don't let the ladies catch on - they will likely call us cads. Or even man-whores. LOL.
So now you know the secret to having your cake and eating it too. You're welcome.
Mmmm, cake...
