Yeah, I'm sure lots of singles brace themselves whenever a married pastor starts teaching about singleness.
Have you ever been to a church with an unmarried pastor, or unmarried church elders? I never have. Name one pastor you know that got married after 25.
Personally, my own home church doesn't teach topically, we go through whole books verse-by-verse and chapter-by-chapter as we go through different books. Of course, there's only, like, two parts of the Bible that deal with that topic, so it only gets covered, like two times every seven years or so. And then only relatively briefly. When it does get covered, I think he mentioned something about "trusting God" or "God's timing" or something like that. We've also had "marriage conferences," but nothing about singleness or dating. When we have weddings at church, the pastor will often comment that God "brings people together," etc., etc.
I also currently work in my church bookstore. For the longest time, the only "relationship books" we had were about marriage, and we didn't even have too many of those. But I did ask them to add some books that I know about singleness/dating, they thought it was a great idea, and some of these books actually sell pretty well, pretty consistently. So it does seem like there was a need for it. Some of the younger folks even started their own unofficial discussion group about one of these books.
I actually think it's be easier for me, a single person, to counsel married friends, than for my married pastor to counsel single people. I mean, I'm generalizing here, but I'd say every single person has read books about marriage. There's thousands, I'm sure. You can even get a marriage book to match your theology.

Everybody has one. Now name the book your married friends have read about singleness. Whoops. There's also very clear scriptures about marriage – what it is, what it is for, what the roles are etc. There's very little about singleness, and a lot of it gets interpreted wrong. And the Bible simply has more to say about marriage than singleness. Sometimes the singleness stuff is just tacked on to the married stuff, as an afterthought.
There might be single people who know more about marriage than most pastors know about singleness.
We also don't have a "singles ministry" at church. I did suggest starting one one time, but the leadership was a bit cool on the idea because they didn't want people attending such a group for the "wrong motives." They said that, if we did have such a group, there would need to be separate ones for men and women. I don't necessarily agree with that, but it was kind of a relief to see that they'd actually given that topic some thought. I just assumed that no one had ever seen the need. I'm also not really sure about how to keep a ministry like that going month after month and year after year because, like I said, the Bible, in totality, doesn't say all
that much about singleness.
Also, I’ve never heard singleness mentioned in a sermon in which sex wasn’t mentioned. Almost every example of a single person in a sermon has something to do with sex.
That being said, cut your pastor some slack and realize that they love you even if they don’t get your situation. Seriously – especially if they try. Pastor’s hearts break for their people. Trust me. I know that to be true. Your pastor is not a mind reader. If you have ideas and they're open to them, by all means, tell them.
