Naughty nurse and her patient, high powered business man and his escort, the single girl and the sexy delivery man -- whatever fantasy gets the creative juices going, there is nothing like a little sexual role-playing to bring some adventure to the bedroom. Whether the couple is in a brand new relationship, or has been together so long they’ve lost count of the years, adding role-playing is a healthy - and safe - way for a couple to flex their sexual boundaries and experiences without any risk-taking involved. Feeling bored in the bedroom? Here are 10 sexual role-plays to try tonight, as well as tips for guarding penis health and boosting performance.

1) Naughty nurse/Patient: Is it cliché? Sure. Has it been done? Absolutely. Still the idea of a rogue nurse risking her job to give him extra special treatment has gotten many a man’s engine running.

2) Police officer/Prisoner: Maybe it’s the chance to use handcuffs in the bedroom, or maybe it’s a sexy uniform; either way many couples love exploring the role of an authority figure behind closed doors. Be sure to take turns in each role!

3) Single guy or gal/ Sexy delivery person: Knock-knock and ding-dong! There’s a special package at the door just waiting to be unwrapped; the sexy stranger will spice things up tonight.

4) Reclusive billionaire/ Secretary: Made popular by the 50 Shades books, what woman doesn’t fantasize about becoming a handpicked lover for a wealthy businessman? Bondage activities are optional!

5) Air Force, Navy, Army Officer/ Wartime Nurse: A man in a crisply pressed uniform does as much for most women as a woman in lingerie does for a man. A quick trip to a costume store or adult fantasy store can produce outfits that will lead to many, many nights of fun.

6) Bachelor/Exotic dancer: Every man would love a private show watching his girl’s sexy moves. Take this private dance to the bedroom for even more fun.

7) Single man/ French maid: All she needs to do is grab a feather duster, a short black skirt and an apron and get busy cleaning his place and the fun will ensue in no time. Remember, her English is terrible, so she may need to be shown exactly what he wants done.

8) Firefighter/ Rescued victim: The classic damsel in distress fantasy makes the woman feel rescued and the man feel - well, manly. Once she is saved from the danger, she is sure to need some mouth-to-mouth resuscitation to help her come to again (and again).

9) Pool boy/ Mistress: This fantasy puts the woman in a position of control. Maybe her husband is out of town, or she’s a cougar who hired a hot young pool boy for some eye candy. While having a pool is a bonus to the fantasy - it is not necessary.

10) Sexy school girl/ Professor: It sure is hard for him to concentrate on his lecture with a girl looking as good as her. With a little extra effort, she is sure to get an A+ on all her homework.

Keeping the Penis in the Game

There are countless other scenarios to get a couple going in the bedroom; just try to choose one that both people are into so they are more committed to engaging in the roles. And, of course, if the boundaries of comfort are being pushed, be sure to have a safe word that will never come up in the course of the role play, such as "tree house;" this will allow both partners to make it known when the fantasy has gone too far.

To make sure the penis is up for anything, men should use a penis vitamin cream (health professionals recommend Man 1 Man Oil) containing targeted vitamins and nutrients that are sure to perk up the manhood, keep the skin healthy, and even improve engorgement to the area. Double bonus if his naughty nurse helps him administer his health cream.
