my penis has been aching when hard, and is stiffer or harder than normal when flaccid. It is the same size as always in both states, but no pain when soft. I ve recently become sexualy active, my girlfriend has been tested and is clean. I have no pre existing conditions. Never had this problem before. It s been almost a month. It gets worse after we are intimate. Do I just need a break from these activities? She s going away for 2 week, will this help?
