It does hurt your neck. Hurts the lower back too! I'm 5'8 and about 180lbs. No action from wife and I had seen other videos. I tried and was about two or three inches away. About a year later I had lost ten pounds a thought why not? I was about an inch away, So I stretched and stretched and was able to lick the tip of cock head. I worked at it for weeks. TAKE IT SLOW!!!! I stretched, sucked in my gut flipping my legs over my head pushing on walls, headboard, couch or whatever . Stretch your neck, back, legs,arms, etc. Drink plenty of water and really suck in that gut. Pull and push your legs and ass down toward you face as you push your feet against something hard. Pull your cock towards your mouth as you reach with your neck and mouth. Imagine and see yourself doing it! Your really have to see yourself doing it. Empty stomach Helps! Remember... Take It SLOW
