25yrs old. 104kg 16th August 95kg 27th August I started taking duromine 30mg daily in the morning since the 16th August. I do go to the gym everyday. Watching porn / sex will surely make me erect hard. Normal ******************* Last week Sunday 24, went over to my GF's place. Got horny, full erected n had sex. Half way through, my penis went soft and shrink to normal. Tried watching porn but it doesn't help either. She gave me a bj and it got erected. She stop the bj, it shrinks back to normal. Am so worried. What's wrong? Monday 25th & Tuesday 26th I watched porn and it doesn't erect at all anymore. When I close my eyes and recall having sex with her, it gets erected a little, not full. Today 27th I didn't take the duromine. Watched porn in the morning, no erection. In the evening like 2 hours ago had sex. Gf stripped her clothes down and my penis got erected but not as usually hard. Eventually it got hard like 70% of normal. Now am back to my home, tried watching porn, it doesn't erect. Someone please help me. What's wrong with me?
