A bit concerned: It would be very helpful for you to see a doctor to determine if your male hormone levels and anatomy are normal. If there's a medical problem, it needs treatment. If not, then just understand that there's a broad normal variation in people's sex drive. Also talk with your spouse about this. If you're both content with the amount of sex, things should be fine.
