The #1 Rule of swinging
It's easy to remember. "No means No". No is not an insult. No may be because of a mood, a rule, or it might mean the other person (couple) is not ready. It may also mean, "No, thank you, but I'm not interested." The reality in the lifestyle is expect to receive rejection. And, be patient!!!
10 Commandments of Swinging
Thanks to Honey Rivers
1. Never attempt to break up a marriage.
2. Always keep dates unless you give ample notice of changing circumstances.
3. Always keep the first meeting on a "no strings attached" basis, but be prepared to swing if it is mutually agreeable or to give an honest answer if something doesn't click.
4. Never, under any circumstances exert pressure on a partner to swing.
5. Restrict discussions of swinging to known swingers and interested persons seeking information.
6. Protect the anonymity of other swingers by refraining from unauthorized "name dropping."
7. Always maintain the highest standards of personal cleanliness and appearance.
8. Do not engage in any unlawful activity that would discredit swingers as a group.
9. Be friendly and warm with your swing partners, but understand that there is a type of emotional involvement, which is properly reserved for a spouse or "primary significant other."
10. Always show respect for the personal attitudes, feelings and "hang-ups" of other swingers.

"On-site" simply means that the function is being held in a private home or a private club. It is widely accepted that there will be some form of sexual activity and nudity at these functions. Aside from the no. 1 rule as stated above, there can be other rules pertaining to the activities themselves. There can be a "safe" room where it is understood that no sex takes place. There can be a private room where no-one is allowed to enter. An open door usually means anyone can enter and participate. These and variations of these rules can differ from one host to another within the same club.

Setting up your own rules
Many couples set up rules for themselves so that each partner understands what is and is not acceptable. This is an excellent idea, especially for beginning couples to safeguard against hurting someone's feelings. Rules can be anything from no oral, to no pain. Whatever each partner is comfortable (or uncomfortable) with. Rules should be explained to any couple that you plan to be with, they need to know what is expected. Don't be afraid to change your rules as you experience the lifestyle more and more. Most couples start out with a few rules, and then they change and change again.
Types of swinging
Soft swinging
Foreplay with other partners, sometimes including oral sex but no vaginal penetration. Can add spice to a couple's relationship & allow them to have fun while reducing the risk of disease or jealousy. Many couples start out as soft swingers as they first explore swinging. But don't think that soft swingers will always convert to full swapping.
Closed swinging
Partners swap, but have sex in separate rooms. Closed swinging allows for a more intimate experience. Some people feel it allows them more freedom to explore & fewer interruptions of their enjoyment.
Open swinging
Partners swap & have sex in the same room, or bed. This includes orgies & is great for exhibitionists & voyeurs, who can show off or just enjoy watching their partner play. Some people find open swinging allows for total release of the sexual desires & fantasies. It is not for the jealous or the shy! ;)
The Allure of swinging
Many couples are sexually aroused at thought of having sex with multiple partners. They explore this interest, and find swinging can improve their relationship, both sexually & emotionally. Swinging can open up many aspects of relationships, both as friendships & romantic relationships. It is refreshing to develop open relationship with people who have similar interests & attitudes.
Other couples & singles just feel that sex is a natural & enjoyable part of being human. Sex, then, is a natural part of friendship between these open-minded adults. These are people who are really can say, "Let's just be friends" & "Friends can have sex," in the same breath.
Swinging brings a lot of communication & openness to a relationship. Many couples find they are closer after they begin swinging. There is no need to keep feelings or desires to oneself. Every aspect of your feelings & preferences can be shared with your partner. They find that not only does their sexual knowledge of each other expand, but their emotional knowledge & communication ability as well. Many couple feel that sharing these intimate acts, fantasies and turn-ons with your mate is a tremendous stimulant.
Lifemate vs. Playmate
There is one thing you should never forget as you enter this lifestyle and grow with your partner. Your spouse is your lifemate, your new friends are playmates. You have decided to build & spend your life with your spouse. Your playmates are for you to enjoy & play with. You should never try to get between your playmates, and you should never ever let your playmates get between you and your lifemate. Regarding your newfound friends as playmates, highlights the fun recreational activity that swinging is.
