Rear Assets Trainer — Trainer Kit by nsnovelties

Rear Assets Trainer User Guide & Play Styles

Starting your anal training with the small plug

The rear assets trainer kit is built around progression, not pressure. Begin with the small plug — at 2.72 inches long and 1.26 inches wide, it’s shaped for a gentle, tapered entry that lets first-timers ease in comfortably. Apply a generous amount of lubricant (water, silicone, or oil-based all work), breathe out, and let the tapered tip do the work. The non-porous aluminum warms quickly to body temperature, so the fit feels natural fast. After you’re comfortable at one size, moving up to the medium or large feels like a natural next step rather than a leap. Keep body-safe materials top of mind — rinse with warm water and toy cleaner after each session. Explore the full anal plug gems range for more options.

Using the graduated set with a partner for the first time

This anal trainer kit works especially well for couples exploring backdoor play together for the first time. The multicolor gem base adds a visual element that keeps things playful and low-pressure. Let your partner help with lube and pacing — communication is the real technique here. The three-piece progression gives you a shared roadmap: start small, confirm comfort, then decide together whether to advance. Personal wellness routine moments like these benefit from having the right tools on hand, and this set keeps it simple without guesswork.
