PA sleeve - any experienced users here?

I’ve just begun my very first chastity lockup using an Emmalock, lasting only a few days. I see this as preparation for the more serious commitment that lies ahead.

So I bought a good quality PA sleeve made of stainless steel—it’s rather pricey—but it doesn’t block access entirely; however, it protects the most sensitive areas well. Link- … SwuzRXd1zZ

Does anyone here have experience with this kind of device and can offer advice, drawing from your own experiences? I’m open to anything: practical tips, emotional aspects, or just general thoughts. Thanks
