Jealous of the Latowski. I’ve always wanted one!
As mentioned before it is necessary to regularly (every 21-28 days) relieve a man in long term chastity either by a prostate milking (more info here and here) or a ruined orgasm. Otherwise most men will be able to orgasm as shown here just by tensing and flexing his abdominal and buttocks muscles. He will be able to do this when he is extremely horny (= most of the time when in chastity) and when the buildup of fluids in his prostate and seminal vesicles is high enough.
