Stickin' to canon. Unfortunately, we probably won't find out what their canonical views on sex or even politics are, so no info on that. That's left up to headcanons and is pretty much completely ambiguous in the show.
You can use stereotypes, but how often do these characters align with said stereotypes? Would Rarity be a slut because "pretty", or is it too "improper" for her prim and properness? Just as likely she'd consider sex before marriage to be improper and such.
So you really can't say on that stuff. Leaving it to headcanon. But here's what's canon about them. Added a bit.
