I'm a 26 year old healthy and recently married male. About 1 month ago I noticed that my erections weren't as hard and firm as they are now. To give a complete picture, usually when fully erect, I am unable to achieve full penetration without hurting my wife. Now that isn't the case. I currently have a legal prescription for focalin and I re-started that medication in February. Also on more than a few occasions I wear a constrictive device around my penis to make sure that blood stays there. Could this be medically related with the medication, due to the constrictive device or is it because everytime I see my wife we have sex multiple times. I can't even begin to tell you how much this has affected me psychologically.
