Do you think it is a good idea to buy your boyfriend a prostate massager as a gift for Christmas?

He hasn’t asked for a prostate massager, he doesn’t own one, only ever used the very smallest butt plug.

I am looking for a sex toy that will help him explore new things such as P-spot play.

Do you think it is a good idea to buy a prostate massager for your inexperienced anal/prostate play boyfriend as a present for Christmas?
