Hurry Up and Catch On Already!

No, they're right, never go ass to vagina. And I think it's okay to comment on it because not many men know the consequences of it and will think it's okay. That would not only fuck up the vaginal PH balance but it would likely give the woman a UTI or other infection. If you want to fuck both holes, just do vaginal first and then anal, but don't go back and forth unless you're using new condoms each time.
