The Nalgina is the fleshy skin flap between the female vagina and in Spanish, the word for little buttox, "nalgita." It is also commonly referred to as the "perenium," "grundle," or the "gooch," located similarly on males between the penis and the chocolate eye.
I rubbed my penis along her nalgina before insertion as a method of foreplay.
