Dear Female Target,
You are at war. The correct way to win this battle is to attack.
Think of his weaknesses. You said he won't say what they are, but that means you can infer that he is aware of some weaknesses. Think about places that are ticklish in you and other people you know. Some sensitive spots that are prime targets for tickling are:
1. upper hips
2. side of ribs near armpit
3. crook of the knee
4. crook of the elbow
5. bottoms of feet
6. base of the neck (around the clavicle)
Of course, wikiHow has an article on how to win a tickle fight. When the article refers to the "victim" that will be your boyfriend. I particularly like the article's "Four-way Tickle" and the deadly "Triple Tickle."
If you still struggle with finding your boyfriends ticklish spots you can quickly win the battle by striking his pressure points. Here is a picture of 3 basic spots on the arm where you can apply firm, direct pressure to quickly disengage in the tickling:
LI 11 refers to the crook of the elbow. LI 10 is just toward the inside of the muscle in your forearm. LI 4 is the inner part of the webbing between the index finger and the thumb, right above the place where your finger bones meet. If you are confused about the position of these points, try them on yourself first. Significant pressure may be needed at first to locate the precise position of the points. LI 11 and LI 10 would be most effective in a tickle fight especially if his hands are tickling you because LI 4 would be out of reach.
Apply the direct pressure with the tip of your thumb. If you have long finger nails and do not want to cut your boyfriend then you could use your knuckle. I would suggest the index finger or middle finger knuckles as shown here:
These same strikes can be used on the upper ribs or sternum for the same effect.
Now for some defensive tactics. None of these attacks will be effective if he is in control. Don't let him pin your arms. If he grabs your wrists you can quickly escape using the techniques demonstrated in this video. I would just add that these techniques can be used while standing, sitting, or laying down. Note how the instructor in the video said to turn your hand so the small part is toward the opening in his grip. When you pull your wrist out, don't pull toward yourself but rather pull in the direction of the opening. Once your hand is free, act quickly to tickle one of the previously specified points.
It may take some time before these tactics become second nature so practice them often. Relish every victory you achieve. Recognize when the tables turn and you gain control of the situation. Practice often and soon you will be having giving your boyfriend a run for his money the next time he wants to start a tickle fight.
You may call this way of tickling excessive, I call it being tactically superior.
