Piss drinking? Advice on how to get started.

I’m a submissive gay male and have a desire to regularly drink my husbands piss “ from the tap” he pees on me and in my mouth there is just some kind of mental block when it comes to actually swallowing. Any advice on how to get past that and actually get to swallowing piss? Thank you in advance for reading and sharing your thoughts and advice!

Update!! I did it haha I finally actually swallowed his piss for the first time and damn was it hot! Thank you to everyone who replied and gave advice, you all are awesome. What a great community here!! Cheers !
