Dildos

A dildo is easier to compare when the measurements are separated into total length, insertable length and maximum diameter. Those figures describe very different things, so a single “size” label is rarely enough. Shape also matters: a straight profile can feel predictable, a curved profile changes the contact angle, and pronounced texture may feel more intense than a smooth surface of the same dimensions. Firmer products hold their shape while softer designs flex more easily. Neither is automatically better; the useful choice is the one that matches your experience, intended use and comfort.
Check the documented material, base design and compatibility before purchase. A wide or flared base can make a product suitable for some types of external or anal play, while a suction base or harness-compatible base should only be described that way when the construction supports it. Use a lubricant that is compatible with the stated material, begin slowly and never force insertion. Clean and dry the product according to its care instructions and store it away from direct heat and contact with reactive materials. Product pages should state what is known and leave unknown fields blank rather than turning a supplier assumption into a safety claim.
