Boyfriend wants to track my phone

So my boyfriend tracks his mum, his housemate & sister all on this iPhone tracker thing that he has.

He keeps mentioning to me about tracking my phone so he can check if I'm okay on nights out... im 21 so still in my social butterfly stage, and he is 37 so pretty much settled and isn't big on nights out.

I have a Samsung so was like oh shame you can't track me, but then last night he brought round an iPhone to give to me (mainly because my screen is smashed and I was saying I wanted a new phone) but he was saying now he can track me..

Is this normal??? For me I don't think it is, and I wouldn't feel comfortable him knowing where I am all the time, irregardless that I'm not doing anything wrong, I haven't cheated before and we have only been dating 2 months???

Help?
