What would you do in this situation? Really need advice!?

Alrighty. I'm a freshman in high school. My boyfriend is a senior. We've been going out for about a month and things have been going wonderfully. Now, however, he's been telling me how a lot of his female friends in his grade all like him now. And I just got some messages from one of them asking me if we were going out because she liked him...uhm...she's in his grade, too. Would you feel threatened by all of these girls liking him? I love him and he loves me, I just don't know what to do about all these girls..=/ I don't want to lose him, he makes me so happy.
