i do all of the above except i don't find it very tight gripped
problems keeping an erection. i'm an 18 year old male i weight 133 pounds and i am 5'8. i have problems keeping an erection it will get hard but it gets soft rather quickly without stimulation like a few seconds. when it is hard it usually stays a sort of mostly hard but still soft penis. i smoke cigarettes and marijuana but not to the extent where it would cause major damage. i exercise 2-3 times a week and eat healthy although i do indulge in some junk food. could i really have erectile disfunction at my age?
