Introduce a Cock Ring
Intensity level: Adventurous
He wears a cock ring, inserted during foreplay, before full arousal. It changes sensation, sustains firmness, and creates a different physical dynamic for both partners throughout everything that follows. Try it during foreplay so you're both used to it before the main event.
How to try this
He selects a cock ring that fits comfortably and places it before reaching full arousal, during foreplay, not after. It should sit at the base. Try it on during the warm-up phase so both partners get used to the sensation before the main position. Different materials have different effects.
Why couples love this
A cock ring changes the physical dynamic for both partners, sustained firmness for him, different internal sensation for her, and a prolonged experience for both. Introducing it during foreplay makes it part of the buildup rather than an interruption, and the novelty of the altered sensation is its own form of exploration.
