I think Miguel'smom is right on target with this in her most recent post above, especially if you and/or your husband are religious or if you are unsure of your husband's reaction.

I am not religious, nor is my husband. I see zero wrong with watching porn as long as it doesn't trigger any negative behaviors, moods, or emotional reactions. I also see nothing wrong with masterbation, or the like, as long as it is done in privacy. My husband feels the same way as me and like me would not see these topics as being taboo. But again, I know others have been taught, or have beliefs, otherwise.

Unless your therapist is very religious or prudish, I would encourage you to bring this topic up with them. Sex-related topics are very commonly discussed in therapy. Most (though surely not all) are perfectly comfortable with the topics. You can always ask first.

Just my thoughts on this.
