You need to talk to him about this. He's hurting you and that's not acceptable. If you are still seeing a therapist together you should bring it up there as well. No matter how out of control he may feel it is not ok for him to hurt you.There are times when things aren't especially comfortable for me, especially because I'm 33 weeks pregnant and nothing is ever comfortable when I'm this huge. But even if my husband and I are in the middle of sex, if something hurts or isn't comfortable I don't hesitate to tell him. He doesn't want to hurt me. We both want the experience to be as pleasurable as possible because it's not just sex, it's about us connecting physically and sharing our love in that way. You shouldn't be afraid to tell him to stop, to ask him to change positions , or anything like that. And if your husband is so controlling that you are afraid, you need to think about whether or not this relationship is the best thing for you. You need to feel comfortable and safe in your marriage.
