One thing I will also note is - and I do mean this in a gentle way - that placing pressure on your child to have children of his own might not just backfire if he's gay. Half of my family is conservative (the other half is progressive) and very Catholic, and my cousin who is infertile has had a terrible time of it. Or if your straight son's wife is infertile. Or if your child ends up disabled and unable to commit to parenting. That may be something you want to work on in the coming decades, partially because if you are a part of conservative leaning communities (like if you're religious) you need to be there for your child if they can't meet those expectations for whatever reason.
What you say is a fair caution. I have not openly told my kid that I expect them to have kids, its just an internal hope. The only thing I really pressure them on currently is trying their best at school and whatever sports they choose to play (the what is up to them except I make them take boxing). If they try their best and still don't do well then its on me for not sitting down with them to explain things they were having an issue with or it just is what it is, no blame. As far as conservative leanings, I'm not religious and prior to reaching my current age was actually fairly liberal (but not the crazy kind). I think getting older and having kids has tempered that and given me more of a conservative political bent but hopefully not the crazy kind :)
