How big is it, really?
Everything below is drawn to the same scale. Exact measurements for this product are in the description further down the page.
Insertable length is the part that actually goes in. Total length includes the base, so it always reads longer.
Girth matters more than length for comfort. If a toy feels like a lot, it is usually the width, not the inches.
New to this? Start below 6 inches insertable, go slowly, and use plenty of water-based lube.
