13 Sex Mistakes You Didn't Realize You Were Making

1.

Opening the condom package with your teeth. Using your teeth (or other sharp things like knives or scissors) to open the wrapper makes it very easy to mistakenly poke a hole in a condom. (In one study, people who opened condoms this way were about three times more likely to encounter breakage. Eek!)

2.

Punishing the pole. Though often stereotyped as a battering ram, the penis is also a highly sensitive organ. Hand jobs and fellatio must be carried out with care. Biting, pulling and strangulation should be avoided unless explicitly requested.

3.

Using lube without reading the label. Betcha didn't know that oil or petroleum-based lubricants (like mineral oil or massage lotions) can destroy condoms, making them more likely to break. Water- and silicone-based lubricants are ideal for use with latex condoms.

4.

Jamming the clam. The clitoris has 8,000 nerve endings in an area smaller than a pea, which means it only takes a light touch to get it's attention. At no time should your hand motions resemble someone who is digging for buried treasure or trying to clear a clogged drain.

5.

Not doing it after you hit the gym. Blood flow to your genital region is higher after a workout, according to one study, making your sexual function go off the charts. Testosterone levels also skyrocket during you exercise, so you'll definitely be in the mood.

6.

Failing to feed your libido. These and other nutrient-rich foods are known to enhance both libido and sexual endurance. If your sex has been lackluster lately, it might be time to take a look at your diet.

7.

Not using a condom because she's on the Pill. According to the Center for Disease Control and Prevention, birth control pills are between 91-99 percent effective in preventing pregnancy, and that number goes DOWN if she fails to take it at the same time every day, she's been sick, she's on certain medications (shall I go on?) Pill plus a condom gives you close-to-perfect protection.

8.

Not having a back-up plan. Pills can be forgotten. Condoms can break. Unless you're in a relationship that's ready for pregnancy, always always have a backup plan.

9.

Forgetting to put lube inside the condom.This is especially true for those of you with lots of stamina: "Always use [water or silicone-based] lube inside the condom. It prevents breakage and plus, it actually feels so much better for the condom wearer," explains sexologist and sexuality educator Megan Andelloux. And just use a drop, too much can make the condom slip off.

10.

"Double bagging it" for extra protection. Wearing two condoms does not give extra protection against leaking. In fact, it actually raises the chances of breakage due to friction.

11.

Only kissing on the lips. A recent survey of both men and women revealed no less than 10 erogenous zones just begging to be kissed. Ignore them at your own peril.

12.

Foregoing foreplay. Foreplay increases dopamine levels, eases anxieties, facilitates natural lubrication and ultimately, enhances the entire experience for both parties. So don't skip it. Even if this is your millionth time with the same partner. Step outside the normal erogenous zones...you might be surprised at what you find.

13.

Not having enough of it. Having sex can improve your sleep cycle, lower your blood pressure, ease stress, burn calories, clear up nasal congestion, fight depression and yes, help you live longer.
