Some guys will try anything to enlarge their penis. Save your money! Creams, pills and “penis pumps” might make your penis a little bigger for a little while, but the change won’t last. In fact, penis pumps can actually damage the tissue and nerves in the penis, if used often. So a guy could end up being unable to get an erection or lose feeling in his penis. Don’t believe those pictures you see either. They’ve been altered to make the penises look like they’re really pumped up.
