Group sex is when a set of four or more people get together to have sex with one another. In this situation, there are no specified partners set up. Dicks go into whatever holes are conveniently around them. Every person engages in a sexual act with someone unique at the party, and people switch partners all the time. Eventually, the goal is for everyone to orgasm multiple times over in the midst of the excitement.
Group sex is not for everyone. If you want to be entirely committed to your partner, this is not the sexual act for you. Such is also the case if you get jealous easily when your partner gets around people of your sex. If you are open minded and ready for a sexual challenge, by all means give this a shot.

To have group sex, you simply need a group of people willing to have sex with one another. Everyone strips down to their birthday suits and begins kissing or fucking other people in the room. Orgasms go off periodically, and men and women alike can get off with this. If you’re a woman wanting to do this, get on regular birth control. If you’re a man, use a condom when you can.
