Several months of clitoris discomfort after urination. No infection. No actual pain during urination. No quality of life!

See an gynecologist. You need to be examined in detail before any clear indication of what is causing this becomes evident. If you have been and nothing found then you may need another opinion from a specialist in this area.
Exam. If you have been experiencing pain after urination for 6 months it is past time you were seen and examined so you can stop suffering. Make an appointment or go to urgent care and feel better ASAP. Hope this helps.
