5. You Smoke.
This one’s obvious. Bad breath, tooth decay, and gum disease—all very unsexy. Lighting up is also proven to cause premature aging and wrinkles—ruining your looks over time and making you feel less sexy.
But smoking has also been specifically linked to lowered sexual desire and performance, likely because it constricts the blood vessels, which in turn restricts oxygen-rich blood flow to your erogenous zones. In men, this equates with a high risk of erectile dysfunction. Kick the habit and you’ll not only reduce your risk of heart disease and stroke—you’ll also boost your sexual intimacy.
