My boyfriend (22M) and I (21F) have always wanted to try sex acts/toys at different times – how do we go about solving this?

We’ve been together a bit over a year and this is my first relationship. Right at the beginning of our relationship, he introduced the idea of wanting to use various sex toys with me – I had no sexual experience prior to him and was very overwhelmed so I asked if we could wait a bit until I got fully used to sex with him. He agreed, and when I was finally comfortable with toys 5 months in, we bought our first item to try.

Since then he has said he wanted to wait longer, as he said we’re planning to stay together for a while so we could do it sometime in the future. So I agreed, but in this time I’ve been craving the feeling for so long. He would constantly promise we would use it, only to “forget” about it on the day. I would have been okay with him saying he didn’t want to use it, but it’s the fact that he would get my hopes up for months. Eventually, I stopped believing him and my interest dwindled over time. I wish I tried it when I had an interest, but now the excitement is gone for me. Recently he approached the idea of wanting to do “everything” with me again, but now I feel neutral about it, I’m no longer excited like I was before. I’m worried this will keep repeating itself in our relationship, how do we go about coming to an agreement?

TLDR: In our entire 14 month relationship, we’ve never been on the same timings of when we want to try sex things/toys and it’s affecting my sexual desire to explore new things.
