Is baby oil okay for vagina?

Sophie

21 female. I've had to use baby oil to put in tampons for years, its painful for me without the oil. Ive never given it much thought until recently I realized I have no idea if thats okay, what if its actually really bad for my vagina? Please let me know, and if its not are there any alternatives? I tried just water before it didnt really work for me. Also if anyone has any advice on why I need it in the first place, my friends have joked that its because I'm a virgin, which is true, as to why its uncomfortable for me. I can only use the smallest tampons they make. Any information is helpful :)
