Welcome to the forum, Ms. Helga!
Good. (But, whenever you wonder whether there are others like you, it's best to remember a truism derived from observation of many phenomena: "If you see one, you can be sure you haven't seen them all." In other words, there are, in fact, other women in situations like yours.)
My husband has turned me into a slut, and I let it happen because I love him.
Well... if that's why it happened, there's nothing wrong with that. It would also be totally acceptable if you let it happen because you're a woman who likes sex, and you require more than one man to satisfy you. There are lots of married women who find themselves in that situation.
Perhaps others are going thru the same situation.
Yes, there are other women in similar situations. Regarding your comment:
"After my divorce, 4 of them, I have been used and humiliated, which is a turn-on for me."
If that's what you need and that's what you've been getting, good for you.
Thanks for letting me join here.
It's a pleasure to have you here, Ms. Helga. Thank you for joining! We'll look forward to hearing about your experiences.
