Been there myself recently and all lads. Felt like a tightness down there, like I was constantly holding onto a piss kind of thing and couldn't relax it properly. Turns out it was prostatitis after an examination, fortnights worth of pills and she was good to go again. Feared the worst because I have a family history of prostate cancer. Its not always the worst case scenario lads, but get it checked out none the less.. ?
