man discovers snap crotch technology, writes dissertation

How do women use the bathroom easily when wearing a one-piece swimsuit or leotard? All of my partners that I've been with have always worn bikinis which to me makes sense and is easy to understand. I can't help but feel like it must be annoying and inconvienient to strip it all off when you want to pee for 10 seconds. Is it as annoying as it seems or is it something I'm not understanding as a guy?
