Is it effective? Yes and no. With a penis pump, your penis really does grow – noticeably so. However as soon as you release the vacuum, your penis goes right back to original size. There’s no evidence of long-term benefits, but they do have one advantage for sufferers of erectile dysfunction: since the vacuum draws blood into the penis, you can quickly roll on a gently constricting cockring after removing the pump, thereby ‘trapping’ the penis in an erect state. While some people who have tried this technique report positive findings, we suggest consulting a doctor first.
Penis size is obviously a factor in the sexual experience, not the only factor, but clearly a major factor. The argument that penis size doesn’t matter seems silly if any serious consideration is given. The mechanics of sex are all about friction, bumping and grinding, and suffice to say an erect penis that is seven inches long and six inches around is going to produce very different friction with a lot more bumps and more grinding than a penis that is 5 inches long and 4 inches around.
Other tips for preventing penis shrinkage such as stopping smoking and optimizing blood flow to the penis may not have a lot of studies to back them up, but we do know there’s a relationship between healthy blood flow and sexual health. Taking measures to maintain blood flow throughout the body, which includes quitting smoking, may not specifically prevent shrinkage but can promote overall sexual health and wellness.
Herbal remedies, Kegels (pelvic floor exercises — learn more here), and exercises have all been mentioned as potential ways to make your penis bigger. However, we’ve searched and searched for medical evidence that these techniques will work to grow your penis, but there’s simply zero, zilch, nada, no evidence. You may find lots of unverified anecdotes, which come from a sample size of one, but they simply cannot be trusted. After all, no one on the internet knows you’re a dog (or liar). We recommend that you avoid these techniques.
