Hello, thanks for using HCM.
Its a good point that your workups with a fertility
doctor did appear normal. Most often low sex drive is associated with psychological issues. Libido or sex drive depends on the state of preparedness of the mind. If you get worked up so much or if you have a lot of issues that pre-occuppy you, being stress
up etc your mind can never be set. Admiring other girls or imagining to be in love with other girls can greatly affect your sex drive.
Hope i did shed some light but if you have more questions, you are welcome at all time.
