Would it be wrong of me to talk to him about this?

I get very easily worried. My boyfriend doesn't always text me back straight away. Most of the time it's fine, but sometimes, it gets to me, most often if he forgets to text me that he's home safe (he rides a motorbike, so you understand why I worry). Would it be totally crazy and wrong of me to bring this up with him? I appreciate that sometimes he's working and shit, I mean sometimes so am I! But can I do anything to make sure he texts me when he's home safe? And maybe get him to text me back a little quicker when he's not working/studying or whatever? Idk, I just get worried sometimes that he's just never going to reply, and then, yeah, idk... Is it a crazy stupid thing for me to talk to him about? It doesn't always bother me, but sometimes it does. What do I do?
