Well, I'm not gonna lie to you and say that it is easy, because it is not. My cock is not that small, so when it gets hard for too long it can hurt my skin. I still don't know how to make to keep it there for longer, but here are some insights and tips on it:

Remove it to sleep

Since during the sleep you usually get hard, it is a good idea to not use it, specially if you are not so small on your cock when you are hard (in my case I have a 15cm hard dick). I know you want to wear your chastity device cage during the day and night, and I had that fantasy in the beggining as well, but lets be real: you can't do that. You need to adapt to what you have. In the first weeks I was on this micro cage device, I tried to push to be locked all the time and I got my skin hurt, and then I needed to stay unlocked to recover. Play it safe to play it longer.

 

Oil and Creams are your best friends.

Yes, your micro cage can cause pressure on your skin, so use oil ad creams whenever you can. If you can avoid issues, go for it.

 

Hot Weather

This can be annoying to wear the cage during the summer or hot weather, because it is so tiny that it does't have much where to be fixed on. So if your cock and balls get too relaxed, the cage will fall off (and you will get upset with it). This issue is easily fixed using a chatity device elastic band, that will keep everything in place (check this article to know a bit more about it).

It might seems nice to look at someone using a micro cage, but behind the scenes it can be difficult. After all, your are "pushing" your cock all way inside your body. So if you want to have it as a lifestyle, I recomend to have different chastity device cages, so you can switch when you need to (or when you feel it too). It is going to be part of you, so why not having different ones as well?
