So i have a gf and she is really amazing. I think i have fallen in love with her. She is starting to want me to touch her chest and below the waist and her butt. She now told me that she was wanting to have sex. I want to have sex with her because she is so special to me and it feels like it will never end with her. At the same time i am scared that things will change but now that i am thinking what could change i cant think of any. I am kinda scared to have sex and so is she but we both want to do it so badly. I am really confused as of what i am to do. Please offer me some advice.

Thanks a bunch,
Jeremy
