Sex and intimacy are naturally associated with love, no matter what guys say here. It is how we work, because it bonds us to our mate(s) and helps to perpetuate the species. Every provider and hobbyist has to learn how to dissociate sex from emotional attachment. Some learn it while hobbying/providing, and others learned it before they got here. Some never learn it.
If you cannot separate those two things, you will not survive long in this world. Others have already explained what bad things can happen when you do not dissociate, so I will not go there.
I fell in love with every woman I saw in my early days of hobbying. I was infatuated, obsessed, smitten, thinking about them and wanting to contact them, learn more about them, spend more time with them. It was wonderful, embarassing, and stupid. I miss it. I was pretty disciplined about not seeing the same lady more than once every couple of months back then, to keep myself safe, and that worked. But when I eventually "broke up" with a couple of my regulars (by a strange coincidence, my two favorites both moved in with BFs the same month, and completely changed the rules), I was very sad, even though these were women I had only seen a handful of times, a few hours, over six months. I needed that to happen in order to get past the infatuation, as it turned out.
Funny thing is that both of them moved out within a couple of months. While that may be some sort of a lesson, I could not go back.
Funny how things change - now I see the same few ladies over and over, no real concern about how often, because the rapport we build, the experiences we share, are something I need to keep it interesting. But I rarely think about them when I am not with them, or when scheduling something. I like them, care about them, but I am not attached to them. If one of them moved in with a BF, changed everything, I suppose it would still upset me, just not so much.
Not saying that is how it will progress for you, just what happened for me. The dissociation thing is absolutely real, and necessary.
enjoy,
