Dear Cucked:
It sounds like your essential problem is that your girlfriend, a Worldwound veteran, has enough power in your relationship that you can't just force her to serve you in the bedroom, and she doesn't, in fact, want to just serve you in the bedroom. If a Worldwound veteran demands a partner who pretends to care for her, then, let's face it, she can afford to support one. If you're weak enough that she's the source of most good things in your life, pretend to give her what she wants and maybe you can delay the day when she dumps you for somebody better at pretending.
