There are no strict rules that you have to follow when you enter into a swinger lifestyle, but there are a few things that we can recommend you and your partner follow.
Enter swinging as a couple
In the context of swinging you should enter as a couple. Being a couple it does not mean that you need to be married, but should at the very least have a little history together. Be familiar with each others; emotional needs and wants. This is extremely important when it comes to feeling comfortable about other couples approaching you in a swinger lifestyle.
Have good communication
This is critical in a swinger lifestyle as you need to be clear about what you and your partner are doing and why.
Confidence and comfort first
Both you and your partner must have confidence in each other when being approached by others. If this is not reached, jealousy will occur. You should be aware of each other comfort when swinging with other couples. If you or your partner is uncomfortable with a situation or activity, it should be stopped immediately.
The rule of thumb is couples should view swinging as a form of enhancement to their existing sexual relationship, rather than to replace a fail one. Swinging is only a form of social activity for both to enjoy and experience together.
Happy swinging!
