First of all why the fuck would this be something that gets my guard up? Anal is amazing and I shouldn't even bat an eye. Yet I'm a bit cautious about this, let me explain.

I'm 26 years old, been with my girlfriend (24) for 5 years. We live together and also have a small child together.

Sex has been great since day 1 and she used to orgasm several time each time we had sex. After she gave birth 2 years ago she lost a bit of her sexual stamina and since then she can't really come more than 2 times then she's done.

I've tried to initiate anal a few times during our relationship but she's mostly said no. About 6 months ago we tried a couple times but she said it hurt and just didn't like it. I left it at that and didn't initiate again.

Now the last couple of months we've had sex less frequently and she stopped initiating as much as she used to. 2-3 weeks ago when we did molly together the conversation got sexual. She said she wanted to try it again and did the day after. She really liked it and we've had anal like 4-5 times since. She orgasms hard when we have it and she doesn't hesitate when I initiate.

She's a very reserved girl and while I've opened her up to more of life's pleasures anal has always been very taboo for her and a thing she was quite cold to.

Now that I'm typing this I feel kind of stupid but I can't ignore my gut feeling that something isn't quite right that she did a 180 regarding this.

Anyone had something like this happen in their relationship, if so did you find out the reason for it, if any? Could it be in correlation with her initiating less frequently and she's trying to add some spice? Maybe she's not as satisfied with normal sex as she used to be?

I'm probably overthinking this but asking for opinions is worth a shot.
