Your husband is wrong, but you’ve waited a long time to do something about it. The fact is that most women cannot achieve orgasm from intercourse alone. You can find that stated in many, many books. Depending on how stubborn he is, you could buy one or up to ten of them and show him that he’s wrong. Or else maybe you could find some man he admires, a good friend for example, to tell him the truth, assuming you knew from this man’s partner that he knows what to do to please a woman. If neither plan works and he won’t budge from his position, then here are some other options. One would be to leave him. I would think that this is not his only fault and so maybe that’s the right thing to do, but I don’t know enough to say and after so long, you may have children and they have to be considered as well. Another option would be to buy a vibrator and right after you two have sex, pull it out of the drawer and masturbate. That way you wouldn’t be left unsatisfied. I’m not sure how he’ll react to that, but it might bring him around. I could suggest that you two go for counseling, but I suspect that he wouldn’t go. You could go on your own, but if he does have many other faults, then the counselor won’t have many other options to offer you besides leaving him, so you need to think about that before making an appointment. Whatever you do, I agree that you shouldn’t live the rest of your life sexually frustrated just because you have a partner who won’t listen to the truth.
