Double Penetration (also known as DP) is a type of sexual activity that involves two or more partners penetrating one another at the same time. This can involve two penises penetrating the vagina, two penises penetrating the anus, or one penis and a sex toy penetrating the anus and/or vagina. Double penetration can be enjoyed by both men and women, and is often seen as an erotic act. It can lead to intense pleasure for all involved, but it should only be explored with caution and consent from all parties.
