Need some help: self referencing many to many relationship between users

I tried to translate the relationship, described in the title, from a project which uses EF, to Orchard.
Originally it has a user model and a UserUser model which defines the relations as follow:
    public class UserUser
        [Key, Column(Order = 0), ForeignKey("SourceUser")]
        public virtual int SourceUserId { get; set; }

        [Key, Column(Order = 1), ForeignKey("DestinationUser")]
        public virtual int DestinationUserId { get; set; }

        public virtual User SourceUser { get; set; }

        public virtual User DestinationUser { get; set; }
What I try in Orchard, is to create a equivalent table to store relations between UserPartRecords.
Right now I have this:
public class UserUserRecord : ContentPartRecord 
        public virtual UserPartRecord SourceUser { get; set; }

        public virtual UserPartRecord DestinationUser { get; set; }

        public virtual RequestState State { get; set; }
(with a corresponding UserUserPart of course.)
This is my current migration:
SchemaBuilder.CreateTable("UserUserRecord", table => table
I also tried the following for creating the ForeignKeys:
                new[] { "SourceUser_id" },
                new[] { "Id" }
The code snippets above are one of a few solutions I tried, but I don't wanna spam them all here. However I had no success in creating a table with two ForeignKeys linking two UserPartRecords together. Can anyone tell me please what I do wrong and where i miss the obvious?

I need a table with two ForeignKeys: SourceUserId and DestinationUserId which are both UserPartRecords. Any help would be much appreciated.

When you say "no success", what exactly do you mean? Do you get an error, or are the tables not being created?

Ah yeah sorry that was a bit unclear.
The tables are in fact created, the foreignKeys are not.

If someone would hand me a small code snippet I would be damn grateful.
Unfortunately I don't have the time right now to look into this issue for hours. :/

Push: also interested in creating a user-user relation.
