Adult only. Private by design.
Sex party rules for a private night

Sex party rules are the lines you say before anyone is in the room. A game night and a children's party are different searches. Guests agree before they answer the cards.
The short answer
Your host invites friends. The host invites friends they'd love to have there. One private link per couple. There is no ticket and no public list to wander.
A yes to the invite is a yes to come. It is not a yes to sex with anyone in the room. A yes to a person is separate, and it is only a match when it goes both ways. A private no stays private. A one-sided yes stays hidden.
Adult only. Private by design. You confirm you are 18 or older. The host still checks you in. All mutual-yes matches are revealed by the format the host picked.
Write one rule per line
Say the night in the first note. Dress, phones, the rooms that stay closed, and whether the night is couples only. Soft or full is a ceiling, not an assignment. Same room or a separate room is where people are, not how far the night goes.
Guests agree before they answer the cards. If you change a line, they agree again. Hold the street until you are ready for people to drive. A place name can go out earlier so they can judge the trip.
A play party already has a longer note on that format. This page is the list you can read for any private sex party you host, including a key party or a speed date.
What the rules mean at the door
Each card is one person. Your own partner is never a card. You can change an answer until answers lock. The group chat opens when someone joins. Guests do not get a private thread with each other. Message host is a private note for the host and co-hosts.
You check people in. They show a door code or a QR pass. They cannot check themselves in. Ask before you touch. Stop when someone stops. The lower yes wins between partners. Either person can leave. They tell the host, and they do not owe the room a speech.
Phones stay down when the rules say so. Do not photograph other guests. Do not repeat a private no to the room. The app does not police the bedroom. The host and the guests do.
The reveal follows the format
On a key party, the room sees one Play Partner together after you start the reveal. On a play party, matches stay hidden until you open them. Then each checked-in guest sees every mutual match. There is no single Play Partner for the whole room.
On a speed date, rounds are about five minutes. Either partner can answer until you start the next round. A match needs both couples to say yes. Pick one format and keep it. When the rules are yours, open the host home and put them in before the first link goes out.
FAQ
Is this a list of party games?
No. Sex party rules here are consent and house rules for a private invited night. Drinking games and video-game nights are a different search.
Is this the same page as play party rules?
No. Play party rules cover that format. This page is the host's list before you pick a key party, a play party, or a speed date.
Does coming mean they will have sex?
No. A yes to the invite means they are coming. A yes to a person is separate, private, and only a match when it goes both ways.
When do matches show?
All mutual-yes matches are revealed by the format. A key party shows one Play Partner at the same time, after the host starts the reveal. A play party keeps matches hidden until the host reveals them. A speed date is short rounds, then yes or no.
