In 45 plus years of pipe smoking, I've never experienced the dreaded tongue bite...never from any blend of tobacco, wet, dry or goopy aro's back in the early days. It sounds nasty. Puffing slow must be the key and I often puff gently for a while and often let it go out and then relight. OTOH I see other guys puffing like a locomotive train going uphill. I don't think it matters what kind of pipe ya smoke either, it's all related to puffing cadence. Sip it, kiss it. Enjoy it.
Oh ! and congrats on spelling " tongue" correctly..probably one of the worst misspelled words in all of history. Too often I see tonuge or tounge. grammar nazi out.
