I have trouble maintaining a full erection, it never lasts for long when i do, and mostly the head of the penis is soft while the rest of my penis is hard, what is the cause of this??
the head will always be soft. maybe if you find you're not getting a full erection it could because of your diet. lots of saturated fats will do it.
yeah but the head usually gets bigger and slightly tighter but this aint the case with me sometimes, also my testicals are loose??
