Gender Reveal Disagreement

Long story short: I have a child from a previous relationship and I found out the gender at 20 weeks. Now expecting my 2nd child and my husbands first. He wants to find out the gender, I want to be surprised. What would you do? I’m leaning towards finding out for his sake since it’s his first baby. Especially since I can’t imagine we’ll have a 3rd child. But then I’ll never get to experience the surprise that I so want to experience! So torn.

Edit: No way in hell he could find out and not tell me 😂 I wish, but I know he’d let it slip within hours
