Scientific observation, seems when young twinks create friction, seems at moment of take off, doesn't feel so good, in that when most 'males' reach that moment, their so over come with high feelings that whole body shakes and vibrates, as if possessed...whole body tends to convulse...but I notice when twinks take off, it's as if 'No big deal'...no shaking, no emotions, it's as if doesn't feel as orbital as with others...just a scientific observation...
