maybe that I do not understand what you really mean, but
\documentclass[12pt]{article}
\usepackage{pstricks}
\usepackage{pst-node}
\begin{document}
\fnode[framesize=1cm 2mm](2,0){A1}\fnode*[framesize=1cm 2mm](3,0){A2}
\nccurve[angleA=-45,angleB=-135,ncurv=10]{->}{A1}{A1}
\nccurve[angleA=-45,angleB=-135,ncurvA=10,ncurvB=20]{->}{A2}{A2}
\vspace{2cm}
\pnode(0,0){A}\pnode(3,-3){B}
\psset{arrowscale=2}
\nccurve[angleA=-45,angleB=-135,ncurv=0.3]{->}{A}{B}
\nccurve[angleA=45,angleB=-135,ncurvA=1,ncurvB=2.2]{->}{B}{A}
\end{document}
