I have to add though that when I was trying to establish my supply (which didn't happen), it was suggested that my H could help! And I'm fairly certain she was suggesting he suckled rather than doing anything else.
FWIW, my H tasted it, and directly from the breast whilst I was still pregnant, although this was a few drops not a nice long drink, and not intentionally, IYSWIM, but if I'd succeeded at BF, I doubt I would have encouraged him to have a drink
