I adore bubble bars! I like them so much better than bath bombs, simply because they bubble
My personal favorite is the comforter, but they just came out with a new one called Dorthy, which has this cute little rainbow on it!
I use my mange too massage bar religiously as a lotion for my legs - just warm it up between your hands until some of it melts into a liquid form, and massage away!
On the whole boyfriend thing, it may be that he's embarassed ( I know my brothers can get like that). If you wanted to get him the acne stuff from lush, just leave it on his bed or in his bathroom cabinet and tell him the tooth fairy sent it lol
