Monogamous... a g/f who works as a SP can actually be quite jealous though we thought it might be the opposite being her in that line of work. But the trade-off is that they are usually extremely loyal and trustworthy. What I meant is they won't go out or fuck some guys for one nighter behind your back besides when she is working. Whereas normal girls these days can go to bed with us tonight and then go out with some dude tomorrow morning when we are at work! Like I said before, in order to differentiate the relationship to "work", both parties have to agree on something that she will never do with clients no matter the money... be it DFK, Greek... CIM... whatever! This way, you know when you and her are together and doing it, you know for sure that is just for YOU and YOU only and she is not treating you like one of the tricks (yeah harsh word but it is true).
Interesting. did you ever ask if you could fuck other girls? not judging, just wouldnt be my ideal set up personally.
most of the people I know who are in one way open relationships, its the guy who is allowed to fuck other girls, while the girl is monogamous. always interesting seeing it flipped.
While its true that there are girls who are cheaters, its definitely not all girls. I still know plenty of girls who only have sex with guys they are in relationships with, although its definitely getting more rare these days.
And I wouldnt be super confident saying that SP's are more loyal, cause I personal trained a girl who is a well known SP before, and she had a boyfriend (kind of the same situation you were in), she didnt know I participated in the hobby, and she didnt know that I knew she was an SP. I ended up hooking up with her a few times for free. Hopefully that wasnt your girl haha. Theres also quite a few studies showing woman who have higher body counts are significantly more likely to cheat.
But again, Im not judging, if it worked for you, thats cool. im just always curious about relationships like yours, its an interesting dynamic.
