Tenga Flex Male Masturbator - Rocky

The spiral ribs really do create that winding motion when you block the top hole—it's like the sleeve is turning on its own. I wasn't expecting the flex to feel so distinct from a standard sleeve, but the twist adds a whole new sensation. Definitely worth it for something that doesn't need batteries

Covering the air hole and feeling it twist on its own is honestly kind of mesmerizing, takes a bit of getting used to but in a fun way. The spiral ribs inside give a texture that's noticeably different from anything else I've tried, and it stays tight without being exhausting.

It does create that spinning motion when you cover the air hole, but the sensation feels a bit muted for me. The texture inside is okay, just not as intense as I hoped for the price.
