Possible.
The main causes of dopamine desensitization are: porn addiction, compulsive masturbation, stimulant use (amphetamine variety), trenbolone use, recreational drugs, some prescription drugs, etc
Receptively stimulating the same pathways desensitizes them then when someone takes certain drugs on top of that it accelerates the rate of desensitization. Result is a person needs more and more stimulus to reach the same feeling. In the case of porn addiction eventually someone needs 20+ tabs open and constant switching to maintain interest.
Another possibility is the OP is simply just suffering from anxiety. In my experience nothing kills my erections or libido more than thinking I might have issues.
What steps would you recommend to recover from dopamine desensitization and how long can it take?
