New To Anal

I have tried

I have tried fingering my butt, and that, but feel id like to get a proper orgasm through my prostate.

Thing is can someone advise i cheapish toy to use, as i have tried the search but can not find a good answer.

I have looked at the nexus range, and wonder if its better for that type of prostate massager or will i get the same feeling from a butt plug.

I say butt plug so i can wear it around the house under clothes and be able to sit at computer too.

Thanks.
