Wanted to buy an all day stretcher to increase length but I'm not sure which route to go. I understand that the Stealth For Men only acts as an extender with a corkscrew. So would this combination be better than something like the X4, phallosan forte, or penimaster pro? Looking to wear 6 to 8 hours at a time to pair with my stretching and bathmate. Which item should I buy if I looking for a combination of comfort and maximizing permanent length gains?
