They're your words, my guy. You didn't say a thing about any of that. You said, it wouldn't be better because women (supposedly) change their minds (about what we want) more than we change our underwear.
Not sure why you felt the need to bring ladies undergarments into it. But that was your poor choice to make. Foolish one too.
All your statement shows is your complete failure to observe the intracasies of female intimate hygiene and that you think we should be able to read your damn minds because you men never say what you mean.
If you think your significant other only changes her underwear once in a blue moon, she's not that invested in you as you claim because shes not trying to entice you into sexual relations or you have harrassed and harrangued that poor woman so much she never had a chance to make up her mind about anything in the first place or you're cheating on her because you didn't notice her strutting around in lingerie which means you're noticing someone else.
Damn.
