How exactly are women castrating men? What are women doing that You're so angry about? Not responding to sexual advances is the only example you gave, anything else? You're doing the EXACT thing you are accusing women of doing, blaming women for all of men's misfortunes.
Except, of course, what your girlfriend tells you. And I'm sure that you're very, very careful NEVER to offend her and to carry out her dream-destroying wishes. If you follow her materialist wishes, chances are you will wind up a miserable bill-paying 9-5er.
