Anyone try prostate massage?

Anyone try having your partner massage your prostate from inside?
I have a case of death grip and I only get 70% hard for penetration on a good day. Gf gets off in multiples from oral , my fingers, penetration and toys. She can’t get me off. She’s great at head and handies, but I just can’t get there. Sometimes she watches as I finish myself and that’s pretty hot! I’ve had a toy on my prostate from my ass years ago and it made me cum pretty hard. Gf is willing to do anything to get me off. I’m thinking of getting a prostate massager for her to try on me….
Anyone done this??

Yes I have prostate toys and dildos. Prostate orgasms are addictive.
