I think as you did like girls before, and asliking boys has only become recent, you don't necessarily have to tell him, as it might just end up it's only a phase your bodies going through, and therefore might just save a hole lot of hassle and problems.
Good luck with whatever you do though! :]
[And the fact that someone said almost 90% of this forum think they are gay, just proves my fact that a huge majority of teenage boys go through this phase and feel as though they are gay, but it doesn't always turn out like that in the end!]
