I have been noticing week erections lately that don't stay hard for very long. And it also seems I can only get erections with physical stimulation but not psychologically. I am only 16 and started masturbating at 8 very infrequently and 1-3 times a day staring at about 12. Oh yeah and my penis is crooked too. Please help me. also could you explain the massage technique because the pictures were not working on your web site.
