You need to consider why you don’t want to be a cumslut, which will take some serious thinking . Then once you figure it out, either way, you will know you made a decision to act on.
My thoughts from what you’ve written, you are worried about what society, or others think of you, rather then what you like to do? Remember this is only one part of you and if you like it, embrace and feel lucky you live in a time and place that you can act on it, 50 years ago, it would have been very difficult to act on your desires to have sex with many different men.
However maybe there is another reason you don’t want to be the way you have been acting, if that is the case, then you need to figure out why and what you want to do about it.
The point is you get to to choose and there are no wrong answers
