Who have you 'heard' from?
For me personally, I like to just be cleanly shaven down there anyway, regardless of who I'm with at the time.
However, you're probably best off asking him directly - some boys mind, whilst some boys really don't care! Furthermore, if you're not comfortable with shaving then you shouldn't feel as though you have to. Just do what makes you feel comfortable!
Personally, at least amongst my friends and I, all of us either shave, wax or use hair removal cream, so I'd think it's pretty normal.
