What can I do with my girlfriend? PLEASE HELP?

you could go indoor rock climbing. that is freakin awesome. i used to do this with my ex girlfriend all the time and took her for her first time and she loved it! you could also take her to a restaurant where you try a new type of food like indian or middle eastern. if you are 18, you could try out a hookah bar. you could also take her to barnes and noble and browse together. my first gf and i used to do that a lot and sneak books from the lesbian section that are a bit naughty and read them together on the down low. its was fun and exciting. hope this helps :)
