Chastity and orgasm denial discussion

I have a query for anyone who knows about prostate milking. My wife has attempted to milk my prostate three or four times recently, with the latest session happening tonight. I’ve abstained from ejaculation for roughly a week now, and my testicles are beginning to ache quite a bit. Since I got my Prince Albert piercing last Saturday, we can’t use that exit route either. So she decided to attempt milking again. Naturally, it appears she is doing everything correctly. We spent an hour with her stimulating my prostate via massage. For the first half-hour, I felt that strong urge to urinate. Afterward, however, it seemed like ejaculation was imminent from my penis. That sensation lingered for about twenty minutes before disappearing without result. Does this sound normal? What other sensations should I be expecting? I attempted relaxing as if peeing and tensing up as if ejaculating. Which method do you prefer? Any advice would be welcome, as my wife is getting a bit frustrated with me.
