You should definitely talk to him about all this. I understand not wanting to hurt his feelings but you’re on a path toward falling out of love and not feeling connected to your husband anymore if you keep all this to yourself and you two don’t work together to address your satisfaction. That might mean exploring your sexuality through an open marriage. Discuss it with him! There are lots of ways to explore extramarital intimacy and maybe there’s a way that appeals to you both and that your husband would be willing to try. Any hurt feelings or awkwardness you might feel bringing it up with your husband would be worth the price if it saved your marriage. And if it doesn’t, it will still be worth it to get out of a situation that doesn’t and isn’t going to satisfy you.
