Baby boy experiences?

So i had my NT test today (12w2d) and all looks good and healthy but the US tech said she's about 90% sure I'm having a boy 😱 I'm actually not surprised cause I had this feeling since the beginning of the pregnancy that it's a boy but now "knowing" it scares me a little cause I have no experience with boys being a girl myself and only having a little sister 😂 so my question kinda is for you mommas to tell me the things you love most about having a boy 🤗 and also did anyone who was told this early on later find out it was actually the other sex? I'll be over the moon either way as long as its a healthy tiny baby 😍

PS: here's my precious little man 💙
