Earliest recorded use for "penis" is 1590s (Shakespeare puns upon it). My prick was used 16c.-17c. as a term of endearment by "immodest maids" for their boyfriends. As a term of abuse, it is attested by 1929. Prick-teaser attested from 1958. To kick against the pricks (Acts ix:5, first in the translation of 1382) is probably from sense of "a goad for oxen" (mid-14c.).
Old English prician "to prick, pierce, prick out, sting," from West Germanic *prikojanan (cf. Low German pricken, Dutch prikken "to prick"); Danish prikke "to mark with dots," Swedish pricka "to point, prick, mark with dots" probably are from Low German. Related: Pricked; pricking. To prick up one's ears is 1580s, originally of animals with pointed ears (prycke-eared, of foxes, is from 1520s).
