Xtend It Customizable Hollow Extender Kit 9 Inch

This has been my go-to recommendation for anyone wanting to customize their experience rather than guess at sizing. The trim-to-fit design means you're not locked into someone else's idea of perfect length — cut the extensions to exactly what works for your body and your partner's preferences. The UR3 material has a realistic feel that doesn't scream "accessory," and the hollow design works whether you need support or want to add to what you've already got. Fair warning: take your time with the trimming. You can always cut more off, but you can't add it back.
