Why ask an obvious question?

Girls on here are always asking if they can get pregnant while having sex on their period, or if they do it in a pool, or if they don't use a condom, or other obvious scenarios that actually get you pregnant. Why don't they just use a condom.. in a safe place, at a safe time? I know they're curious and before I didn't know those things either but c'mon I see the questions asked too often and it's getting old. Like that is what this app is about. Read the information it gives us before asking a stupid obvious question.
