Difficulties with wearing a device? discussion

Hello fellas:) I’ve been trying to get over the first night in chastity for at least a year with many different devices, the ones I found the most comfortable were HT knock-offs, but I have this problem with the rings in every chastity, There always appears to be one of either two things, either some of the chastity manages to slip off during erection, so it kinda brakes my cock, and it never manages to get back inside the chastity as comfortably as it was in the first place, and make erections terrible at night. on the other hand, if I take any base ring that is smaller than that, the device feels snug and nice on my member, but the ring manages to crease my ball skin cause the ball skin’s diameter would be bigger than the ring. and those spots that are hidden in the creases turn red and painful (probably due to eczema) Is there any way around either of those problems? has anyone gone through one of them? Thanks in advance, XOXO
