An erectile dysfunction assistance device is an apparatus that supports the entry of a flaccid penis of a user into an orifice of a participant by widening the opening of the orifice of the participant. The apparatus includes a tubular brace, a domed insert, and a flange. The tubular brace supports the shaft of the flaccid penis and widens the orifice for the flaccid penis to be comfortably positioned within the orifice. The domed insert widens the opening of the orifice and supports the head of the penis into and within the orifice. The flange stops the tubular brace from entirely slipping past the opening of the orifice and allows a user to grasp the present invention while positioned within the orifice and around the flaccid penis. The tubular brace, the domed insert, and the flange are separable along the length of the flaccid penis for painless and easy removal.
