"...after having sex I feel like a stupid for giving in"? If you are married, have a good relationship with your husband, and have started a family together, you're not "giving in". It's part of the joy of being in a commited loving relationship. "Giving it up" is more high school speak, like you gave in on a date and let some guy grope you in the car. You're not at that place anymore. However, you may need to mention it to your doctor; it could be that your hormones are a little out of balance or something. I'm not a doctor, not even going there, but there are reasons that women's sex drives wane but a doctor may be able to help you find why and help "fix" it if you want.
