Been over a week since sex 😩

I’ve been with my bf for about 4 years now and we usually have sex like every few days. There’s always those moments where we won’t do it for a week, but once it’s over we do it quite a bit. This time around, we haven’t had sex for 8 days. So far this is the longest we’ve gone without it. I’m not sure if it’s due to stress on my bf, as he plays college football and just started school this week. He keeps telling me it’s coming and that once it does we’ll do it a lot and to not worry, but I can’t help but not worry. Is this normal for anyone else out there?!
