Indent for second line of chapter/section title

Question

I have got a simple problem concerning multi-line chapter/section titles, that I could not fix.

This is how it is:

and this is how I want it to be:

(I want the second line of the title to line up with the first one)

I have read somehow relevant answers who use the titlesec package. As far as possible I want to avoid that. I read a few pages in the KOMA guide but without a solution. Please tell me, if you know some KOMA-options or KOMA-commands to fix this.

Thank you in advance.

edit: I am sorry, but I forgott the probably most important thing: used \newline or \\ because the hypertension was ugly.

MWE: I noticed, that I made a mistake in the description of my problem. I used \\ or \newline to break the line. Here the MWE:

\documentclass[%
a4paper, 
11pt
]{scrreprt}

\usepackage{lipsum}
\begin{document}
    \section{Title long enough to flow in the second line\\ and indent matching the previous line}
    \lipsum[1]
\end{document}

Answer 1

Using \newline instead \\ works for me:

\documentclass{scrreprt}

\usepackage{lipsum}
\begin{document}
\tableofcontents
\chapter{Chapter}
\section{Title long enough to flow in the second line\newline and indent matching the previous line}
\lipsum[1]
\end{document}

But note that the same line break will be in the table of Contents. To avoid this use the optional argument of \section:

\documentclass{scrreprt}

\usepackage{lipsum}
\begin{document}
\tableofcontents
\chapter{Chapter}
\section
  [Title long enough to flow in the second line and indent matching the previous line]
  {Title long enough to flow in the second line\newline and indent matching the previous line}
\lipsum[1]
\end{document} 

Answer 2

Check this.

\documentclass{article}
\usepackage{lipsum}
\usepackage{titlesec}

\titleformat{name=\section}
  {\normalfont\Large\bfseries}{\thesection}{1em}{\hspace{0em}}{}
  \begin{document}
  \section {Title long enough to flow in the second line and indent matching the previous line}
  \lipsum[1]
  \end{document}
