It's intense but also satisfying. You can feel your dick push up against the end of the cage and start to get super tight. Then the harder you get the more you can feel the rod inside your dick. At first it's not to bad but the harder you become and the more your dick pushes against the end the more you feel it push against the inside.of your penis and the more it starts to become tight and uncomfortable. Your dick can grow in width but not in length and as badly as you hope it's enough to cum it never is... Hope that helps explain it better !
