Okay I understand that you are not a native speaker of English, fine, and biased of context clues and that one sentence (“You should have a good mouth too, if you want to have a girlfriend you should know how to talk sweetly to the girls.”) you can infer that what you meant by “licking” was sweat talking her, but here’s my question, where in the world do you live to possibly think that the word lick/licking could be used that? I mean this is not me or anyone having a dirty mind here, To my knowledge there is no other possible way to interpret a sentences like “If he wants a beautiful girlfriend then he has to learn how to lick!”, followed by, “After so much practise (practice) he finally got a girlfriend!”, in a clean way.
