Being fit and at a healthy weight has a lot to do with how a penis appears and performs (more on that soon) but it also has a lot to do with what we eat. For example, foods like onions are said to increase healthy blood flow and circulation — including to the penis! Salmon is known for this as well, and so are bananas (we’re trying not to make a pun here) and dark chocolate. Also, foods high in protein (say, like eggs or low Greek yogurt) and proper hydration can only work in your favor.
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.
