The ladies we see are actually real human beings with wants, needs, and desires of their own.
I have had such relationships in this life style, none of them ended badly, and I treasure the experiences.
It totally depends on what you want, what she wants, and what you are willing to accept to make such a relationship work out if that's something you both want.
Are you going to be friends with benefits? something deeper?
You'll have to figure these things out for yourself.
If you decide to embark down a more personal path there is something you must absolutely do.
Be honest with yourself, and her.
Will she continue working? Are you able to accept the fact she's having sex with other people or because you have something "special" will that change things for you? Can you make that adjustment?
I can, but I know I am in a very small minority in that regard.
Will you continue in this lifestyle despite being in a more intimate relationship with someone who knows this lifestyle, and will you be open and honest with her about what you are doing?
It's a lot like any normal relationship, because it is, you just have a few more wrinkles to pay attention to.
If you want to make an attempt at this I would suggest trying it but my advice would be that both of you be very honest, and very clear, about what this thing means between the two of you, and set ground rules for both of you right up front about what you are both comfortable with and that works for both of you.
Because as I stated, the ladies we see are actually real human beings with wants, needs, and desires of their own, and any relationship ultimately works best with setting ground rules for both of you and being honest with each other.
And for Keerists sake man! Enjoy it while you can and don't push and ruin something amazing!
