There should be 5-15+ guests in order to have a party.
Make sure the space you choose is clean and tidied before the party.
Make sure you have enough food for each guest! Take into account any dietary needs of your guests.
You might have to make/order two desserts if you are having lots of guests. You can make the cake rainbow or ice it white on the outside and make the inside rainbow. You can alternatively make treats iced and decorated as your own pride flag (i. e, a pink, orange, and white cake if you’re coming out as lesbian).
If you want your coming out to be a surprise party, don’t make the invite about you coming out. Simply say it’s an “announcement party” where you have something important to say.
It doesn’t have to be serious when you come out. Make it more entertaining by including a pun, such as, “I asked my friends whether or not they understood what it meant to be pansexual. I couldn’t get a straight answer!”
