I want to spice up sex life

So I’ve been with my husband for a very long time. We were both pretty young. I had bfs in HS but never anything serious. I got with him right before I graduated HS

He’s only my second sexual partner. Sometimes our sex life is eh. Never really has been all that great. I can’t really get off.

I love him more than anything but the lack of being sexually happy does affect me at times.

Sometimes I wish we could have an open relationship and sleep with others. He works way too much and rarely has time for himself so it would end up being me sleeping with others and not him. Which wouldn’t be right. I do have fantasies of experiencing others sexually since I never got that Opportunity. He’s my second and I’m his second. Both priors were only 1 person 1 time for us. So way lack of experience with others.

I enjoy my life with him, we have so much to be thankful for , it’s just the sex. Yes we have toys and have tried things but never lasts. I wish he was more go for it in the bedroom but he seems like he’s still not shy but just doesn’t go for what he wants.

*Added**

We’ve been to a sex shop lots of times many many years ago. We have lots of toys, just doesn’t get used much. Our sex life is what you would call Vanilla. I think after 10+ years I’m just kinda bored of not having orgasms. The only time I ever do is using a vibrator on the clitoris. We have used it during sex but it can’t be used every time ...
