We can't help you out with most of life's big, important decisions, but we can tell you that with this sexy inflatable penetrator offering from CalExotics, you can be as undecided as you like - at least in terms of dildo thickness!
Thanks to a unique blow-up ready layer over a nice firm core, the Inflatable Stud 9.5 Inch Dildo starts off (relatively) small and sleek, but can be pumped up to nearly twice the thickness during play. To experiment with different sizes, just squeeze the attached bulb. Hit a dedicated quick release button to shrink the Stud back down to its default size.
In smooth latex (allergy alert!), the Inflatable Stud is easy to clean with warm soapy water or a good toy care fluid/foam. Compatible with any great quality water-based lube.
* Featured measurements represent the Stud at its at default (un-inflated size).
