Whats something i can say sweet to my girlfriend?

If we had to tell you what to say, then it wouldn't be coming from you. Would it? By you "running out of things to say", you are basically telling me that what you have said is all lines. Let her actions lead your heart. Your heart will speak on its own.

Haha, you're sweet. It's hard to say because none of us know your girlfriend at all, much less as well as you do, so I can't say anything in particular. But I would probably start focusing on things that other people don't know about her, aspects of her (physically or her personality) that only you know about. Or, you can focus on littler things...her skin, her hair, her lips. Girls like to know that their guy thinks they're gorgeous, but they also like to know that the guy likes them for who they are inside. It's always a good sign when someone continues to open up to you and you still like them, even after you know the pros and cons to that person. So, if I were you, find some little things about her that are more specific to her that only you would notice.

Shane,

Well you could ask her if she knows the difference between sex and conversation, if she says no, then tell her to take her cloths off and lie down on the floor as you want to Talk to her. I am sure she will see the funny side and you'll have a laugh about it.
