Sex help?

I’m in a pretty big pickle that i want to fix asap. So I’m sure a lot of people have been in this situation but can someone please give me help. My boyfriend and I have been together for about a year and 6 months and have always had super great sex. Like I use to look forward to it so badly and crave it. Key word: Use. Lately, it’s been so un-enjoyable for me and I hate it!! I don’t know why either :( So, what can I do to get this back? I’ve been getting bored of sex lately. And trust me, we’ve tried vibrators, handcuffs and all that jazz. So someone help a girl out, how can I get a fun exciting sex life back? Is there anything you girls always turn too! I love my man, but I’m missing the exciting sex!
