The story

The Shaft Model F is an 8.8-inch realistic cock sheath in the brand's proprietary Flexskin liquid silicone — softer than standard silicone formulations, with a skin-like flex that makes the toy feel less like rubber and more like a body. Sized to extend length and girth while staying comfortable for the wearer.

Liquid silicone is body-safe and compatible with water-based lubricant; silicone-on-silicone degrades the surface, so skip silicone lube. Wash with soap and warm water, air-dry fully before storing.

Good for: couples adding length without committing to vacuum work, anyone wanting a realistic sheath softer than typical silicone. Mahogany colorway.

Questions before you buy?

Will this arrive in discreet packaging?
Yes — all orders ship in plain, unmarked boxes with no product names and no brand logos on the outside. We ship discreetly on every order, automatically.
What's your return policy?
Sex toys can't be returned once opened — that's an industry-standard hygiene rule, not specific to us. For defective or damaged items: we'll replace or refund. Email us and we'll handle it.
Is this product body-safe?
We carry only products that meet our editorial standard: body-safe materials, no phthalates, no BPA, no latex in products marketed for internal use. Our board sets the bar; this product meets it.
How do I clean it?
For non-motorized toys: warm water and mild soap, or a dedicated toy cleaner. For motorized or electronic toys: wipe with a damp cloth and toy cleaner — don't submerge unless the product is rated waterproof. Waterproof rating is noted in the specs section when applicable.
Is this rechargeable?
Check the specs section on this page for charging details. Most modern vibrators and massagers include a USB-C or magnetic charger. Battery-powered products are noted clearly in the Materials & specs accordion above.
Can I order anonymously?
Yes — guest checkout is available, no account required. We ship in plain packages with no external branding. The charge on your card statement appears as "Alexander Institute" — the parent company that owns Loving Sex, nothing that identifies the product type.
