Such enemies existed in the past-they were fighting for glory on the battlefield or victory over an enemy of the faith-and one could argue that they pose a threat today as well. Things are much better if the conflict concerns something that can be split up-such as money or land. Then you can bargain with your enemies to divvy up whatever you disagree about and you can have something like peace.
Rather than repeating myself here, check out this guide for restraining your partner during sex. This will allow her to control your position, pace, and pressure as you eat her out. She can even get a little rough by pulling your hair and grinding her pussy against your face. This also has the added benefit of allowing her to push your head away if her clit becomes too sensitive after orgasm.
