A Fun Night Turned Serious?

Hey there! So last night I was just chillin', watching a movie with this new friend of mine. We’ve been hanging out for a couple weeks, pretty casual stuff. But somehow the vibe got super heated and before we knew it, things were getting pretty intense between us. It felt like one thing led to another in an instant. Now here I am feeling all flustered about whether we crossed some kind of boundary or if it’s totally normal to get carried away sometimes. What do you guys think? Is it just me being paranoid or should we have talked more about expectations before getting physical? Am I overthinking this whole situation or is there a clear line we shouldn’t cross without talking first?
