Penile Sensitivity

Let us talk about penile sensitivity
Anybody found a method to increase
I am down to about 0-5% now no matter what I do, which porn Im watching or who Im with
I have normal T levels, in good health but yes I abused porn all my life. Nowadays I legit only watch porn every 3 weeks or so to test if I can feel something and it doesnt work. Really good erections.

Things I have tried
Horny Goat Weed with Yohimbe - works sometimes, what holds me back is yohimbe over time will give anxiety
Maca - tastes too bad for me to take it for 4 weeks straight, yes even the pill has a taste
Man 1 oil (cream) - does not work
Celery - definitely works sometimes if I eat a very large amount
Kegels - works if I do a whole lot every single day
For celery and kegels, it isnt sustained
Long periods of nofap - works but then I flatline fast
Cialis - makes me numb as hell
Viagra - makes me numb if it ever does work

Can you elaborate a bit: with the items that do “work” for you, are you referring strictly in terms of senstivity, or other aspects like erection quality, libido?

Also: how long have you flatlined? I ask because the theory goes that one will pass through the flatline stage to good functioning if one persists.

Thanks, I am interested in this subjecdt of sensitivity as mine is on the low side and I am seeking to improve.
