P Zone Advanced Extra Thick Prostate Anal Massager by Icon

The good news is, it stays in while I'm walking around. It's my first purchase of prostate toys and butt plugs that will stay in.

The bad news is, it's a little too short like every other toy I've purchased, with the exception of a hand held vibrator and a 7.5" thrusting cock like dildo with a suction cup.

I would like to have something that I can wear out and about while flexing down there to stimulate my prostate.

Does anyone have a suggestion? I would need something over 5", probably 5.25"-5.5" would do it. Yes I've tried many Aneros models with no luck.
