When updating database I get a EntityValidationError - asp.net-mvc

Question

I'm trying to get the logged in user to edit his profile. For now I decided to use a satic userID (since using the sessions usedID was also giving me errors). Now when I run the code it goes through all the lines but at the end it gives me this error "EntityValidationErrors".
I just want the code to update the current UserID's Bio, Sex, and preferred sex
[HttpPost]
public ActionResult FillProfile(tblUser user)
{
using (TrinityEntities db = new TrinityEntities())
{
var id = Session["userID"];
user.Id = 1018; //Convert.ToInt32(id);
SqlConnection conn = new SqlConnection(#"Data Source = (LocalDB)\MSSQLLocalDB; AttachDbFilename = C:\Users\Ruben\Desktop\Periode 2\Persoonlijk\Trinity\Trinity\Trinity\App_Data\Trinity.mdf; Integrated Security = True; MultipleActiveResultSets = True; Connect Timeout = 30; Application Name = EntityFramework");
conn.Open();
string Query = "SELECT FirstName, LastName, Email, Password, Age FROM tblUser WHERE Id='" + user.Id + "'";
using (SqlCommand command = new SqlCommand(Query, conn))
{
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
user.FirstName = reader[0] as string;
user.LastName = reader[1] as string;
user.Email = reader[2] as string;
user.Password = reader[3] as string;
string Sage = reader[4] as string;
user.Age = Convert.ToInt32(Sage);
break;
}
db.Entry(user).State = EntityState.Modified;
db.SaveChanges();
}
conn.Close();
return RedirectToAction("Index", "Home");
}
}
View:
#model Trinity.Models.tblUser
#{
ViewBag.Title = "Profile";
// prevent login by alterring adress
if (Session["userID"] == null)
{
Response.Redirect("~/Login/Index");
}
}
