*laughs* Then you'd better pray to god that your BF doesn't want any children as well, otherwise you're in deep shit.
But anyway, adding on to your rambles, there also happens to be some girls that are soooo hungry for sex, that they would get it on with a bunch of men, & after a few rounds, whoops, you're pregnant. & of course, it's also possible for a girl to have a few too many rounds of unprotected sex, & that'll also result in them getting pregnant. & you know what, I actually knew a female that did such a thing, & wound up pregnant. I was absolutely baffled that she isn't an emotional wrecking ball at the time, as I thought that being a single, expectant mother would the the perfect recipe for one.
Anyway, I'm also the same as you, as I, too would never imagine myself being a father. As a matter of fact, I'm the kind of person that would eat their own young.
