Anal vibrator for shower

Hey everyone, I am looking for a long thin anal vibrator with a girth less than 3cm but with shower cups so can stick to the wall for solo pleasure. Can't find any so need advice and help please

I meant girth less than 3 inches

I can't find anything either which fits all the criteria. Most dildos which vibrates and have a suction cup are 5 inches in girth. Most anal vibrators don't have a suction cup. Couldn't you start with a regular dildo, without the vibratons? :)

Thank you so much. That's the dilemma. There is no perfect one for beginners in this category. It's one of the two no combination.
I hope they start making one which fits this criteria :) thanks for the advice :)
