I don't mind little gifts or surprises once in a while, but I wouldn't want to be showered in them. I wouldn't like him always paying for everything either... I make my own money, so we usually split the bill unless it's like a birthday or something.
I don't say no if my boyfriend wants to treat me once in a while... it makes him happy and I do it for him sometimes too. I just wouldn't want it to be something that happens all the time. I don't want to be spoiled... constant gifts makes each one less special. Just getting them once in a while makes all of them special.
