Prostate Fix-Up, Prostatitis, BPH

Is it typical for a man with chronic prostatitis to receive a prostate massage from his doctor?

I just discovered that my husband’s doctor has performed prostate massages or milkings to relieve pressure and that during this procedure he actually has an erection and has something called a “non-genital” orgasm. Has anyone else ever heard of this? He tells me that it’s not at all erotic and can be sometimes painful. Is this something that I could do for him at home? His doctor is an attractive young woman and I’m not crazy about the idea of these “milkings”.
BTW… I don’t want to ask him to see another doctor. She’s tops in her field and I want the best care possible for him.
