I literally am having the same thing that happened to you! My clit is red and swollen and I noticed a little white dot the size of a pin and it doesn't come off easily but with warm water and some manipulation it finally gets off. Did you ever get tested and figure out what it is?! I'm pretty anxious and just wondered if u could ease my mind :) lol
Testing is not as bad as you may think, ok lets say you have chlymida...would you rather fing out now and get it treated before it became a bigger problem? I am not saying you have it, just used it as an example, because like I said the symptoms don't match up to a STD.
I am still having this symptom off and on..and I have also noticed a small white dot the size of a grain of sand on the base of my clitoris once you pull the hood back. I tried to get it off thinking it was a discharge and I cant..it hasnt changed in size or texture or anything..I believe I am starting to lose my mind..I wish I could stop being so OCD about my body and leave the thoughts of having an STD behind. I think I should go get tested but Im scared to do that too...omg!
Never heard of a STD that would cause your symptom. Never hurts to test if you have never tested before to know you status. Testing is recommended yearly if not in a relationship.
