Several 4 months ago or so randomly the left side of my penis head(nurve endings) starting to feel very sensitive and irritated. I was freaked out by this and it didn't know what happened. I went for around 2 weeks without masturbation or intercourse. Most of the sensitivity went away. Although, occasionally I will feel a little of the same feeling but not nearly as sever on my left side of my penis head. Can anyone give any input?
