I’m actually in a healthy relationship and it’s weird?

So I’m pretty much used to toxic relationships (not cheating or abuse, just not necessarily healthy). My first love slept with his ex while we were on a “break.” My second left me cause he was moving but then had a new gf a month later. My 3rd was always really distant and never talked to me. And now I’m with my 4th and he’s perfect. We’ve been dating for just over half a year. I feel really safe and secure in our relationship, and he treats me amazingly. And this might sound shitty (I’m definitely not going to leave him) but I’m kinda bored. There’s no drama or anything so we just have to rely on each other for entertainment. So what are some ways to spice up a healthy relationship and make it more exciting?
