If it seems like a responsibility, there's a chance there's a lack of romance and a presence of tension in the relationship. If you and your partner don't agree on how often you should have sex, be aware that many couples share this situation. It’s not abnormal, and it doesn’t mean that you and your partner are necessarily mismatched.
Still, you need to resolve the issue and that can best be accomplished by talking it out. While an honest discussion about sex may not be easy, it's best to put your discomfort aside. Sex chats can provide partners with a variety of benefits.
They can help the both of you build trust just by going through the process of revealing very personal thoughts and feelings. You two also have an opportunity to come up with a plan that works for you and your partner. Getting to something you both can live with is better than uncertainty. It makes it easier to manage your expectations so you won’t have to wonder if you’re ever going to have sex again.
When sex feels more like a responsibility, this might mean that you are not sexually attracted to your partner anymore. All couples would need a certain level of intimacy in order to stay attracted to each other. They do not need to have sex all the time but they should be attracted to each other to stay together.
There is also a possibility that sex feels like a responsibility because your partner is lousy in bed. You may feel like you are only doing your duty because you are expected to do so and not because you actually feel any sexual desire for the person that you are with.
