A month or so ago I had a cramp in my taint while laying down. I jumped out of bed and it went away. It felt like a muscle cramp. Since then I think my erections have been weaker and so have my orgasms. I'm going to stop masturbating to see if it goes away by itself but it has been a month. Could it all be in my head? Has anyone experienced something like this before? I'm 26, healthy, not taking any medication, not suffering from any injuries or health conditions, and not grossly overweight.
