How come my new male guppy that I bought to mate with all my females, doesn't show any interest in breeding them?

Hey my name is Karla nice to meet yall I love to chat and chat with new people and I love to play my clarinet and I hear music, my favorite song is Blank Space from Taylor swift, which Taylor Swift is my favorite celebrity, I'm Mexican-American though when people ask me what race I am I say Mexican idk why but Yep. I am a nice person, I love to eat tho I never get fat, (weird) So Whats Up...
