「Wisely controlling both arrays」in a sexual partnership helps prevent unwanted infections, and one way to do so is by both individuals discussing and promising with VOWS not to violate the trust of the other person by cheating sexually…it may be assumed here that both persons are reasonable, and reasonable people feel guilt before breaking a vow.「Yield, submit, change directions of, break the will」with「sexual foreplay」mean exacting a VOW from a partner of some sort, such as not engaging in sex with any other partner and to remain sexually monogamous.
　Nevertheless, elements also are「breaking one's word」that suggests any VOW or OATH is worthless in actuality, since psychopathic liars can vow things, too, without remorse, and even good folks might not be able to resist some offers of「talented hands prick teasing with intercourse.」Best practices require not relying upon any vow or oath of another person for anything believed to be important.
　「Use hands」with「hatchet」or,「pawing and scratching constantly like a prick-teasing pussy」「to flay, fillet, debark, remove skin」and as「break someone's will, bend, turn a corner, change direction, yield, submit」「submit to words」「yield to words」「words that bend, fold, turn」one's behavior are a PROMISE, OATH, VOW, PLEDGE, SWORN STATEMENT.
　Elements individually are「talented hands with subtle and malicious prick-teasing intercourse」that suggests a process used to exact a PROMISE, OATH, VOW, PLEDGE, SWORN STATEMENT from a client or one's lord.
　「Using talented hands to accomplish a task while wielding a hatchet」is universally recognized as an effective means for exacting most any sort of PROMISE, OATH, VOW, with the threat of enforcement constantly looming over the promisor's conscience and skull. Note however that some forms of duress are no longer permitted by the courts as a method of creating a legally enforceable contractual promise, but it still works pretty good [sic] in actual practice if not employed excessively. Be aware that any vow exacted under duress will not likely be honored by the swearer, eventually.
　Monogamy was generally unusual except for some few women, being thought of as unnecessary and unwanted by most everyone, and given the fact that no one on Earth was sufficiently gullible to ever believe it in the old days anyway, so this type of pledge was rare other than for married women for whom it carried the penalty of death.
　Also possible is a serious pledge not to physically attempt to「fold, spindle or mutilate」anyone's genitals during sex (never an unreasonable request), regardless of how promiscuous he or she may have been recently and therefore the need to revenge oneself upon man- or woman-hood using a hatchet, cleaver, upper and lower incisors (that make 'incisions'), rusty box cutter, dull edge of a spoon, etc.
　Scholarly explanation:「use hands chop words」into a wooden tally used to record contracts and presumably refers to the bending and breaking of that wooden tally into two parts used to signify a promise or contract, with each party retaining one of the halves.
