Trying viagra once made things worse

My issue is that I had intermittent psychological ED. However I tried viagra once recently. Ever since my penis feels almost rubbery and my ED issues even when masturbating are 10x worse. I can’t find anything online about this type of things. My dose of viagra was so small and the half life is like 4 hours. So it doesn’t make sense why it’s causing me issues a week later.

Has anyone else had this type of experience?
