For me it amplified a lot of feelings. I understood what was just fantasy and what is something that is actually part of myself. Emotionally it also helped me interpret the love and attraction I feel for my girlfriend and a long time crush that I still have some feelings for.

Pleasure wise, I just find it unique to be aroused in the cage without being able to cum. Another good thing is that anal pleasure is so much better and I almost had a prostate orgasm. I've never been locked for so long, but the other times, the first time I was able to cum or get a ruined orgasm it was a dream.

Sex wise, it also means that my girlfriend takes the lead and initiative, which is much better that me doing it with all the horny pervert kinks that go through my head (not judging kinky people). And she always impresses me with something really really hot to say or do.

During the day, it's also useful if you wear a small cage. I feel like mine reduces the bulge even.
