Couple days ago I've notified these very very small flesh bumps on my shaft, not fluid filled and not painful. One raised bump seems to be a straight line very small. Looking for some answers
If they've always been there, they could be Fordyce spots, which are normal. A pic would help though. This should help you add images:

If you're using a phone or tablet, you may need to choose the desktop/PC option in your browser.
Sounds like a scratch... but yes picture would help
