Boyfriend

Hi guys, I'm looking for a bit of advice.

My boyfriend is the most amazing guy on the planet. But he's so insecure. I really don't know how to make him feel better.

We have sex 1-4+ times a week. If we only do it once or twice, he thinks something is wrong. Admittedly, I have been way less in the mood for really no reason.

He feels like I have no interest in him when I talk to him all day every day, and we work together a day or two a week. AND I spend the night at his house three times a week.

I really don't know if I'm doing something wrong. He's the love of my life and I don't want to mess it up. And certainly not because my sex drive has gone down or because he seems to think I have no interest..
