im 18 years old and in the past few weeks its been getting hard to get hard. i hope its not a serious issue. i dont even wake up with the good old mornng wood anymore. don't do much jerkin anymore either.
If there have been no lifestyle changes that you have gone through that are causing it... Jelq.. Google instructions and start a routine of 10-15 minutes 4 times a week. I guarantee you spontaneous erections like you were 14 again.
