Hello. Thanks for posting your query.
You have described that you have a less sexual drive. But you haven't mentioned about your erections. There are two possibilities in your case.
1)Low sexual drive with erections- hormonal imbalance
2)Low sexual drive without or weak erections Erectile dysfunction.
I would like to recommend you to consult a physician to have a complete check up including physical examination, hormonal analysis and regular lab tests in order to land on a diagnosis.
Hope this helps
