Not important. We’ve been doing a bunch of GROWN UP STUFF LIKE “PAYING TAXES” and “CHECKING THE ECONOMY”😎😉🤠 just kidding we been having sex. Like a lot but not a lot. The first time we do it we did it raw. But its all good because hey. I’m not pregnant. I wanna kid just not now. AFTER THAT I WAS LIKE IM NEVER DOING IT RAW AGAIN 😤👎👌. Spoiler alert we did because we were just in that mood and shit. We always use condoms and stuff because no babies because skool first am I right HAHAHAHAHAH 🏫📚🥇😂🤪🤟 THIS IS WHERE I ASK FOR ADVICE FROM YALL GODDESSES OF THIS EARTH ❤️❤️😍😍😉: how do I tell my Padre that I am sexually active and would want BC for the fact that I’m not tryna be prego right now.
