When you are able, you need to add a two stage cylinder pumping routine to your arsenal of weapons to fight turkey neck. This cylinder pumps balls and dick together and pulls the turkey neck down to your scrotum as your balls increase in size with the pumping action.
After you come out of the cylinder, I would recommend a cock ring BTB that is comfortable for you to wear most of the day. ALSO, I recommend a comfortable cock ring to be applied on your ballsack above your balls. That will draw the turkey neck down to your ballsack area. If I had to wear just one cock ring after I pump two stage, I would use the one around the ballsack above the balls. It pulls the skin down off the penis area into the ballsack area.
Try it. It works for me and I have a moderate turkey neck I hate. Your mileage may vary. Additionally when you pump your nuts, they get bigger and you get a mild bounce in libido by bringing blood down to your balls.
Good luck.
