[QUOTE=JackHolly;7463185]I'm not a doctor, but wouldn't the change in pH for a girl, only last for a few hours? Especially if she's peeing after sex (as we all should be) and / or rinsing with water after sex?
Also, the PH in a vagina can change due to stress or diet, so unless the women who have told you that had specific medication conditions, it seems like they might have been misinformed in saying they can't have semen in their vagina. But then again, I'm not a doctor, so I could very will be mistaken.[/QUOTE]Pee does not clean semen out lmao. The urethra is not in the vaginal cannal unless there is some birth defect. And cum stays in women for quite a while, unless douched out but even then you'd have to really rinse it out fast and douching can fuck with pH too.
Also all people's bodies are different, you can really attribute one ph changing factor to all women.
A quick anatomy video could teach y'all a lot if you're actually curious.
