so im 18 now, going to college in 2 days. ive never had a girlfriend, never known the touch of a woman.

but theres a girl who is amazingly hot. she likes me for some reason. she is so beautiful the sun would not rise without her.

now i am pretty sure she will want to say goodbye, but the only problem is i cant think of what to do with her tomorrow or even what to say.

want to come to my house?... sounds too direct
i want to say goodbye?... then what?

im open to suggestions here.

Feed her some datura, then follow her around.

You're going to collage, you've waited too fucking long. You've wasted your chance, I can almost say it's completly pointless to try and start something unless you have some kind of sick fettish for "tEh cYbERZZ SEcKZZZZz!"..
As well, if you hadn't been in a relationship before it's going to be real weird for you. And maybe more so for her..

From an optimistic point of view..
Ask her out for coffee, have someone throw a little "going away" party.. Something of that sort..
