Better Fit. Better Control. More Confidence.

Why Fit Matters

The pump creates vacuum. The cylinder determines how that experience fits you.

A properly selected cylinder can help provide more consistent vacuum control, a better seal and comfortable room for temporary expansion during use. LeLuv offers a broad range of internal diameters, lengths and flange styles because one cylinder does not fit every body or every preference.

HOW TO MEASURE

Measure First. Choose With Confidence.

For the most useful starting recommendation, take measurements while fully erect. Measure twice for accuracy.

STEP 1

Measure Girth

Wrap a flexible measuring tape around the thickest part while fully erect.

  • Keep the tape level

  • Keep it comfortably snug

  • Do not compress the skin

  • Record the full circumference

  • Measure in inches or centimeters

Important: Do not measure straight across. Girth is the complete circumference around.

STEP 2

Measure Length

While fully erect, measure from the base to the tip along the top side.

  • Begin at the base

  • Measure in a straight line

  • Record the measurement

  • Do not use flaccid length

  • Allow modest clearance beyond your measurement

Your cylinder should be slightly longer than your measured erect length.

Choose How You Prefer the Cylinder to Fit

Recommended starting point
Balanced Fit
Choose the internal diameter suggested by the LeLuv size chart. Best for balanced clearance, predictable sealing and easier pressure control.
Keep My Recommended Size
More Lateral Room
Experienced users who prefer additional internal width may consider one size step larger.
Adjust Length Profile
Choose a cylinder with modest clearance beyond your current fully erect length.
Choose length without adding unnecessary unused space.
Cylinder dimensions determine available internal space. They do not guarantee permanent anatomical change. Temporary expansion varies by person and session.
CHOOSE THE FLANGE STYLE

Next, Choose How the Base Fits

Rounded Flange

Best for: A comfort-focused starting profile for many users.

  • Rounded transition at the opening
  • Comfortable base contact
  • Most common LeLuv style
  • Multiple internal diameters

Wide Flange

Best for: Customers who prefer broader base contact.

  • Wider contact area
  • May improve seal stability
  • Fit varies by anatomy
  • Available in selected sizes

Thick-Walled / No Flange

Best for: Experienced users seeking a straighter-wall profile.

  • Thicker acrylic wall
  • Minimal or no flange
  • Accessory compatibility
  • Best for experienced users
