In the early stages of dating, it’s a good idea to avoid touchy topics. That said, much of this depends on the dynamics of the two parties. Some people thrive on bringing up some of the topics you mentioned, such as those that are about sex, religion, politics, or an ex. That said, the safe bet is to avoid these topics when it is still early.
Other topics that have a risk of causing annoyance on a date are those about money and socio-economic status. This can be misconstrued. One party concludes that the other is a financial opportunist, while the party that brought it up is thinking about mutual financial solvency. It’s best to keep topics fairly generic in the early stages of courtship, until a camaraderie and rapport has been established.
