Sex drive?

Okay so I need help. I'm in my early 20s and I think I have a low sex drive. The only time I'm actually horny is right after my period but other than that I don't need sex. If I'm kissing n touching and getting some foreplay then yes I'll get horny and have sex but I never initiate anything cause I don't get horny! Is this normal? I hear all these stories about masturbating before a first date so you don't have the urge to have sex or having sex every day and I'm here like that's not me...
