Need some advice.

Hi I am fairly new to butt play. So far I’ve used the B Vibe Snug Plug 2 which is 1.2″ and the Ubberime Splendid Medium dildo 1.5″. I am looking for a prostate massager specifically so I can have both hands free. Someone suggested the Njoy Pfun massager. They said they got a super O from only that toy. I’m still interested in Aneros just because they are so well known. I’m really having trouble making my mind up. Any advice is appreciated. Thanks
