Naturally, many men don’t listen when their partners speak to them with signals during bedroom acts. But before you go screaming at your husband, you’ve got to make sure you’ve been as clear as you think you can be.
You said you are too shy to voice your needs, but I don’t think you have a choice here.
The next time you and your husband are on it, and he does something you like or enjoy just tell him softly, “Honey, that feels fantastic! I love it when you do it that way.”
Such words are encouraging, so he’ll most likely adjust to make you more happy.
