Does never fap cause to PE? Masturbation can be use to cure PE so this is why im asking or i wonder if someone experienced this?
Desensitizing your penis can help. Scar tissue or benzocaine would do that, but the bigger issue is in your head. PE is more mental than physical. Thinking more about the process than about the end result helps. Talking to your partner, complimenting them, can also help. After an early misfire, instead of withdrawing and leaving, you can continue enjoying sexual contact, and you will do better on the second round. They say, 'Third time's a charm.'
Wouldn't this also numb your partner? It's like gaining an ability to last longer by forcing your partner to last much, much longer.
DISCLAIMER: Consider this "general advice" on PE since you're under the legal drinking age: I find that if I have one or two drinks before sexual activity, it slows my brain response just enough that I can last much longer. You have to be very careful with that, though--one or two drinks only. Drink much more than that, and you'll end up with "whisky dick" and you won't be able to maintain an erection at all.

Its right up there with PMO as an escape from life. Keep your life full and interesting and you won't be tempted by alcohol, drugs, or PMO. Life can be enjoyed. Do it!
