Size problem? Or do I not have a prostate?

Hi,

So I have an MGX. It just feels “kind of nice” while in, unless I start normal masturbation. Then when I get close I can feel a ton back there **if** I also push on it. If I go hands free, the sensation back there falls off a cliff and dies.

Do I need a bigger Aneros? Tbh people say “find your prostate with your hand” but I have never found anything back there.
