So, can you get preggers if like your bf rubs his dick and shit when there could possibly be Pre cum and then finger you? Or what if he like cums on your boobs and then like you shower but idk cum somehow goes to your vag😂 OR what if he like cum in his underwear and like grinds on you. OR what if you lay on some sperm. idk I know this could sound dumb but I’m SO SO SO paranoid about getting pregnant so like I think about the worst situations. So someone pls help
