I have no money. My boyfriend won't buy me a vibrator?

I want one for valentines day, but he says since he would have to go online and he uses his credit card, his mom checks his statements, even though he's 19. I'm 19 as well. I really want one but i'm so broke and i'm worried about picking it up in the college mail room if it says it's from a toy place :O what to do....?
