Is "sucker" or "lollipop" slang for something else?

. . .I'm with you (so I might have a dirty mind). . .but I would guess it is the 'oral' thing since I saw a program on how young'ins these days are all doing the 'oral' thing (pretty rampant in schools) and that they don't consider it 'sex'. . .but not an expert on current slang. . .
