Hello everyone.....I found that my dick gets irritated sometimes when I use the size genetics extender...so I've been doing some research on how to make it Alittle more comfortable and I ended up stumbling upon a vacuum extender that works by using a vacuum instead of your dick. I'm just posting here to find out what you guys think of it and if anyone has ever tried it. Dld I would also love to here wat u have to say about it too. I've also included a screenshot of the extender on amazon. Thanks.
