My husband and I have been married for five years and have two small children. over these years he has convinced me to do a lot of sexual activities I thought were not a normal part of a marriage and I am morally against. I understand that things like watching porn together are relatively normal and although I am ok with it now I have not changed my opinion on it. One thing I was adament on is that I would never have a three way. When I'm aroused it's hard to not get into sexual things that I otherwise have absolutely no interest in. meaning i've tried for long enough to satisfy him that i have gotten myself to get hot about things he likes, not me, so that he enjoys it more, and, after some fights and him being depressed over it and saying he'll be depressed for the rest of his life and he should have done it before getting married, he took advantage of that and convinced me to do a three way. I tried to lay down some rules like this will be the only time cause he knows I am against it, but he kept talking as if he plans on convincing me to do it a couple times a year. the more I think about it, the more I want to say no, but i'm afraid of the consequences. we had a large fight over this and we rarely fight. and it would be cruel to have promised something that he says is so important to him and then just change my mind and i really don't want him to be depressed and resentful for any amount of time. how can I get him to remember the love he has for me and how he used to not want to push me into it because of the hurt it would cause me? it seems like he just can't get enough when it comes to sex. by the way five years ago the first time he told me he had watched porn he had felt extremely guilty about it.
