New Doctor refuses to prescribe me tretinoin?

I’ve been using tretinoin(0.5) for a few years now. I even used it for a brief period of time in high school. It was never an issue getting it prescribed by whatever doctor I was seeing. I moved and I have a new doctor now and she refused to prescribe me tretinoin because I’m not on birth control. She claims tretinoin causes birth defects and said something about how if that happened with me she would get in trouble. I tried to explain to her that I’m single and celibate but she tried to insinuate a bit that I could be lying or it could still happen and that she’ll prescribe it only if I’m on birth control. Is it me or it this ridiculous? Not only that but I don’t even want children and I don’t understand why she just assumed my sexuality? Why would I pay to get birth control and risk getting horrible side effects for no reason? Even when I was on accutane years ago I was allowed to not take birth control because I was abstinent. I’ve never heard a doctor say this about topical tretinoin. Is this normal? Do your doctors tell you that you must be on birth control?
