Recently, on several occasions, I heard this talking point on the radio: Topics To Avoid On A First Date.
Based on this article
https://www.elitedaily.com/dating/conversation-avoid-successful-first-date/1833702, topics to avoid on a first date are:
1. Your Ex
Never ever talk about how awful your ex was.
This makes you look bad, and you could come across as looking bitter.
2. Money
Never discuss finances. Don't talk about how much or how little you earn.
Talking about money can sound like you're either bragging or stressed. Just don't.
3. Politics
This is too heavy a topic for a first date, and could get very intense.
You don't want to lose a second date due to difference in political opinion.
Just because you feel strongly about certain things, it doesn't mean your date needs to hear about it.
4. Religion
This can be a very personal thing, and could get too heated.
5. Family Background
You may have had a terrible family upbringing. Maybe you had an abusive dad or an alcoholic mom.
Whatever the case, this is simply too much to bring up on a first date. It might end up sounding more like a therapy session.
6. Sexual Experience
Don't talk about how many sexual encounters you've had, or how much you date.
You don't know this person yet, and this is a very personal and private topic.
7. Marriage
Don't talk about how you're ready to have kids and get married. This will scare your date away.
This is something you can talk about only after a significant amount of time has passed.
8. Sex
Don't talk about how the person turns you on, or how much you want to take him or her back home in order to have sex.
It's a turn off, and it just makes you look creepy.
9. Secrets
Don't share your deepest, darkest secrets with someone you've just met: He or she simply hasn't earned your trust yet.
Moreover, this is extremely inappropriate, and will probably not be received well.
10. Work Drama
Gossip is exhausting, and you aren't in high school anymore.
Instead of talking about water cooler gossip or how much you hate your job, talk about your passions and ambitions.
