DAMN, man. You can't just wanna fuck her or start kissing her all over the place straight away dude.
You have to show her the real stuff.
A way to a girls heart is through poems, preferably your own, and flowers.
Yes flowers. What? What's the problem? It's romantic. If you are embarrassed in front of your friends or something by giving your girlfriend flowers, then dude, you seriously have to grow up.
Pretty much that.
