Meh: You made one post yesterday. Most posts usually get responded to fairly quickly, but sometimes stuff slips by. We're not supermen. But if you're going to give up because your posts don't get answered, you're in trouble as PE is 90 percent "grit" (that is, sticking with it).
As for your questions, the penile slapping is a way to get blood flowing back into your penis after a stretching workout. You can kegel or gently slap the penis. It's also good for getting blood moving throughout the penis (great for warming up_.
The leg tuck pull is a form of stretching. It targets the ligaments, one of the key areas to target when doing PE.
The fowfer is great for keeping the penis extended, similar to an extender. Put your penis in this position for 20+ minutes, and it helps similar to how most standard stretches do. It also helps extend the flaccid penis.
I'm not sure I understand question 4. Can you reframe it?
I hope these answers help! Good luck and remember, patience is a virtue
