Hey

Im dating this girl, and its really all good for us and shit I like being with her, but today after partying with her she went home and I kissed some girls.

I believe in TRP theory and shit and I know no morality, but fuck, we are men, we have values and morals. There is a big chance she will never know but still. Should I tell her? She is young and Im the first boy she is dating. Like lets be honest, being drunk is no excuse and Im a fucking asshole for doing this, but what would you do?

Act like nothing happened or tell her?
