We've said it before and we'll say it again (probably another few times after that, too!): we know that sometimes, you don't need or want anything more than your very own left or right. But for those times when the good ol' grip is feeling a bit same-old, may we suggest an upgrade? Doc's Main Squeeze Endurance Trainer, for instance? 

Aside from a super-discreet plain black casing that's a breeze to travel stealthily with, this classic-with-a-twist handheld stroker lets you deep-dive into a pussy textured for maximum stimulation. It'll help train you to stay firm and steady, even in the face of over-stimulation. 

Totally customizable in terms of tightness, the Trainer features a wide plate on the firm outer casing that yields to the pressure of a holding hand- just squeeze to increase friction and grip. Craving an even tighter fit? The base cap can be loosened (or removed entirely) to control inner suction.

In Doc Johnson's very own body safe ULTRASKYN material, the Trainer is extra easy to clean and maintain. This stoker dissembles quickly for clean-up, pop out the sleeve and rinse it well using warm soapy water or a good quality toy care fluid/foam. It's very important to let the insert dry completely before storing it away, so leave it out in the open until then. 

Something to note is that the Trainer (and all Main Squeeze strokers) requires a LOT of lube to help things glide along smoothly, so make sure to stock up before your session- a good water-based lube is your best bet, avoid both oil and silicone formulas, as they can break down the material. 

* The Main Squeeze Endurance Trainer features approximately 7.5" (19.05cm) of penetrable length. It's 3" (7.62cm) in width and 9.5" (24.13cm) in circumference.
