I Have Reached An Internal Erection:-$

When I was using the cb6000s and trying to get hard, I’d fill the tube first then pull my testicles away from me, which felt uneasy. With the JB model, since it sits right when soft, I notice it doesn’t tug my balls out; instead, they just swell up on the inner side of the a-ring, like an internal erection. On one hand this is better than how the cb6000s work because there’s no pain and it feels great. However, does it potentially lead to harm? I believe Thumper brought up something regarding this occurrence before but couldn’t locate that discussion back then. What do you all think?
