Lend each other - In a swinger or sex club or by dogging, for example, you want to lend / "rent out" the other or each other.
Lending or "lending" yourself in a swinger or sex club or dogging means that you are open to having sexual experiences with other people. It can be either lending your partner to another person or lending your body to others while your partner watches or participates.
This can be an exciting and naughty way to explore your sexuality with your partner or alone.
It's also important to remember that this is not for everyone. It requires trust and openness in the relationship and good communication with your partner. It's important to take the time to consider if this is something you're interested in and if your relationship is strong enough to handle it.
