My penis is not soft in a flaccid state. It is always a little hard even when in a flaccid state. It is also a little painful when squeezed and after sexual activity. The color of my semen is always mild yellow. When I urinate, it takes four or five minutes to empty the bladder. It comes out fully, but then the last bit takes longer. I feel like the muscles in that area are constantly tight. My testicles get sore easily if they are squashed or I sleep on them. It feels like the penis is constantly engorged with extra blood flow and makes me feel aroused when I do not want to. For instance, when I urinate, even its touching seems to stimulate it easily, with no sexual thoughts. But if I have a sexual thought on other occasions, it also responds very quickly without much time. I only have very little control over it. When it get erect for the sexual activity, it does not feel the same sensation as it used to. Instead, it feels rubbery. It never used to be this way previously. I also find that the unwanted erections and hard flaccid state are much worse for three days after sexual activity. It never goes away, but it is terrible in those days. Because it is firm and looks semi-hard under my clothing, it can cause a great deal of embarrassment and unwanted impressions. Please help.
