A man concerned about penis sensitivity should make sure he gets the above vitamins via the regular use of a top-notch penis health creme (health professionals recommend Man1 Man Oil). Why a crème? Because of its topical application, it can deliver those vitamins directly to the penis itself. But there's another reason: A really good crème will include other important ingredients that can interact with those vitamins for a synergistic health effect. For example, a crème that contains acetyl L-carnitine and L-arginine "doubles up" the crème's penis sensitivity power. Acetyl L-carnitine is a neuroprotective ingredient that helps preserve nerve sensitivity. And L-arginine is an enzyme which is involved in the creation of nitric oxide, which, like vitamin C, helps improve blood flow to the penis. So for the man interested in keeping his penis well-sensitized, a crème like Man1 Man Oil is best.
An itchy penis is something that all men experience at some point or another. When that itch is chronic, however, it can be inconvenient and embarrassing - for both a man and his partner, who doesn't like to see him constantly tugging at his crotch in public. (No matter how much a guy tries to be inconspicuous about scratching the penis, he's bound to be caught occasionally - and when he has a chronic itchy penis, he's bound to be caught more often.) Tending to penis itch requires proper penis care, of course - and some men may want to consider including their partner in that caring process.
