My fiancee loves it shaved..... I don't know why but I guess its fun for him.
What ever feels comfortable, try it both ways then see wich one you and your boyfriend prefer.
It all depends on you, do you like it or not, don't let somebody change the way you look to satisfy them, its your body do what you want.
Don't worry hun, it just hasnt happened yet, it will. All in good time.
