My girlfriend always gets skid marks! Should I talk to her about it?

That's gross. Why doesn't she notice, she MUST. You can't do bathroom business without noticing your panties, they're right there in front of you when you sit down! uming she has regular female genitalia. Obviously. Though it is very embarring and you need to talk to her about it since you're living together, so you already seem like a serious couple. Or just get her some pantyliners.
