1) your not entitled to sex (seeing your replies where your trying schedule sex like it’s a Sunday dinner is wild) 2) you guys should be practicing informed consent. Conversations about what you need what you don’t like. I spy she’s not getting everything she wants either cuz laying motionless is obvious discomfort. If she doesn’t want to discuss the issue you stop having sex until she brings it up. I have a feeling the relationship will naturally fizzle after this.
Oof this will not end well. Someone this self absorbed about only getting off for themselves and not considering their partner is selfish. And from the sounds of it you already tried to address it and she whines about being a pillow princess she is never going to try and help. Better off breaking up.
The main thing is that its not just about her, but also about you. Yes you guys are in a relationship but the only way a relationship can work is if you communicate and feel comfortable doing so. Sit her down when the time is right and just tell her how your needs are not being met, and ask for a change. Your feelings matter in the relationship too!
it’s just so hard, i legit just tried to set something up. we hang @ on campus often, but we’re both dorming. spontaneous hookups are hard. i just straight up asked, “when can we set something up?” and she just said “i’m too busy.” i said “all week? what am i supposed to do?” and she said “idk. figure it out. i’m good though.”
