Since scohe001 already did a good job of explaining the issues with your answer, I will focus on your assertion that Wrokar's answer is no better than yours.
While it is true that Wrokar's answer does not explicity say "I was in this situation, I did X, and the result was Y", all of that information is still contained in their post, albeit in a less intuitive way. They mention having similar experiences
I've been in my own gay relationship for 5+ years, and we've had very similar experiences in the past. I am closer in personality to your boyfriend (looking to talk about personal life all the time), while my husband is similar to you (not very talkative, especially when there's nothing new to talk about).
They also mention that their solution to the problem has been to find a balance, which has required both to put in effort.
It has been a challenge for us to find a good balance on how much to talk and what to talk about, and has required effort on both of our parts.
Reading from an earlier paragraph we see an example of how to find that balance. The less vocal party makes an effort to find things to talk about while the more vocal party lowers their expectations of the amount of conversation.
Perhaps he can lower his expectations a bit when it comes to your conversations, and/or take the lead when it comes to conversations and be the one who does the bulk of the talking. Simultaneously, you could put in some additional effort to have more things to talk about. Maybe volunteer with an organization? Join a local book club? Take a class at a community center? Set up a weekly night out with a friend?
