Test And Dick Stops Gettin Hard!! Help

EVERY TIME IM ON A TEST ....AFTER A FEW WEEKS I CANT GET HARD, I THOUGHT U WERE SUPPOSED TO BE HARD ALL THE TIME..MAYBE I GOT THE WRONG INFO....BUT WHY DOES THIS HAPPEN.....AND MAYBE A MONTH AFTER IM OFF THE JUICE I GET HARD ALL THE TIME......SINCE IT MESSES ME UP DOWN THERE LIKE THIS.......CAN IT ALSO MESS AROUND WTIH SIZE? OR NO

THANX FOR RESPONSES!!

REally weird...When im on test i turn to supernympho man. Ive read that high test doses can supress libido, decreasing sexual desire. Whats your stack are u on deca or fina too or maybe on a dht blocker. Those can really bring u down - no pun intended.:)
