question: For about a month my penis was extremely itchy and stayed a reddish color. About two weeks ago i started pulling with coconut oil. Couple. Days later i decided to bath with it. Later that night my penis had swelled just a little bit and itched a lot more. Swelling went away after i took an allergy pill. Two days ago blisters appeared in my mouth and a large 3/4in blister on my penis. The one on my penis popped. It is very sensitive and hurt/burns if anything touches it.
