Very odd ..

So like my boyfriend and I have been having sex , a lot like usual (TMI) I know but we're all mature women here right ? Anyway we haven't been doing it with condoms lately and he has litterly came like 30 times inside me and oddly enough I haven't gotten pregnant , I kinda want a child but maybe it's just not my time yet ; and I'm perfectly fine with that. I just sometimes wonder if something's wrong with me or him.. I just don't know . If i Should be worried or glad .
