Question About Skin Pain

I’ve been using the Size genetics for about six months now. I have only managed to get about 625 hours in it so far, and it has been painful. I have tried using the noose system, but it continues to break after only a few times using it. Then I switched to a Velcro strap, which was working way better for me. However, now I keep getting skin sores right below my glands after using it for only a few hours at a time. I wrap my penis in first gauze, then an ace wrap and that does nothing to not prevent the sores. Does anyone have any ideas to keep from getting skin sores? Also, this was the only place I could post, so sorry if it’s the wrong place to do so.
