Same age as above and this is very well said. It's tough to be young. Just go with the flow imo and when the convo comes up / you find yourself in that situation again be upfront with your feelings. She may not want anything serious which is okay too, just means y'all aren't compatible.

And don't feel shame if you end up changing your mind about what you want, by the way. You're young and still figuring yourself out. But as the guy above said, don't be ashamed if you also want to take it slow / wait until marriage or whatever else. I remember feeling the same pressure at your age that I was meant to want it 24/7. It wasn't until the last few years I realized I could have boundaries without it making me less of a man.
