My gf is bad at sex

When I(29m) met my girlfriend (33), I was a little insecure because her body count was much higher than mine. She said she enjoyed sex and was a sexual person.

The first time we had sex, it was good, hot and in the moment. Looking back, it was good because it was just our first time together and it was spontaneous. But I did everything. After the next 2-3 times, I started to realize that she didn't do anything. She just laid there.

I eventually brought it up that I'd like her to do a little more stuff, take some charge maybe, new positions, something. She said she'd try, but it's been super minimal.

We do the same two positions. The same order.

I like her outside of sex, I think she is beautiful and funny and fun to be around, but she is absolutely boring in bed. I want more but I don't want to constantly be complaining about it.

Edit: it's not just positions we do, but the effort. I'm doing all the work. I want to feel like we're both having fun and enjoying it. After a while, i get tired and interest drops, and she's the only one getting anything out of it.
