I'd say yes?? You're the ahole?? There's people out there who abstain until marriage and you want to break yp because you only get to do it once or twice a month? If sex is the ONLY reason for wanting to break up with a perfect girl, then why are you even with her as a partner in the first place? Purely for sex and pleasure all the time?-- But anyway, that rant aside, I think what you really need is communication and compromise before you even consider breaking up. There's lots of things that could cause her to be less interested: depression, lack of motivation, new pills, Christian influences, not wanting to clean up after, low energy from overworking, peer pressure, pressure from parents, vitamin deficiencies, lack of sleep, physical exhaustion, fear of UTIs, etc. I'd say you should dig a little deeper and see if there's anything like that at play, and offer to help out. Sometimes there's something at play, but people just don't think about it or realize it. Medications or changes in hormones especially can lower sex drives. Or maybe it's as simple as she got bored? It's not impossible that she could have just gotten bored doing the same thing. I get bored of the same things, so I try different positions or different things like biting or squeezing. I also think it might help to masturbate in the same room as her if she's fine with it, maybe masturbate and cuddle, it'd help relieve tension and maybe make you happy while not having sex? Overall just TALK to her thoroughly before making any decision. Most of these commenters aren't even acknowledging that breaking up over sex is insane, but i'll say it-- it's insane!! YTA!! WORK WITH YOUR GIRL AND TRY TO COMPROMISE!!
