He doesn't want sex as much as I do

My husband and I are in our mid twenties. We've been married for a year and a half. Together for 4.5 years.

He's kind of always been like this. Though, before we had ever had sex, he was always so horny. It's been frustrating throughout our entire relationship but I'm at wits end now.

He doesn't watch porn, he isn't cheating, he is healthy, he is happy, he still finds me attractive.

He used to watch a lot of porn when he was younger. I feel like that may be part of the cause.

I just need to know I'm not alone. I need to know if anyone else has dealt with this and found a way to help.

My husband just doesn't want to have sex as often as I do. We have sex about 5-6 times a month. Which may seem normal, but 90% of the time, I'm the one who has to initiate. To seduce him. To get him in the mood.

It's exhausting and depressing.

I know he loves me, but it makes me feel unloved.

What can I do?
