Creating a Dynamic ActionLink based on Identity

I'm sorry for the beginner question, but I can't figure this one out.

I'm trying to use my own UserId I have set to navigate around the site, rather than the AspNet.IIdentity

For Example, I have a link to a Profile page which works find when it is hardcoded to the UserId

Snippet from _LoginPartial

 @Html.ActionLink("My Profile", "Details", "Users", 
      routeValues: new { id = 5 } , 
      htmlAttributes: new { title = "Profile" })

but I can't get it work dynamically.

I created GetMyUserId action to use, but I just get to work when I call it.

Other attempt for _LoginPartial

@Html.ActionLink("My Profile", "Details", "Users", 
     routeValues: new { id = Model.GetMyUserId() } , 
     htmlAttributes: new { title = "Profile" })

UserContoller

   public ActionResult GetMyUserId()
    {
        string currentUserId = User.Identity.GetUserId();
        var userId = db.Users.FirstOrDefault(u => 
                     u.AspNetId == currentUserId).UserId;
        return View(userId);
    }
