I always fuck my ltr of 2 years pretty rough, hair pulling, choking, slapping, etc and she’s always submissive.

One nuisance with me is that she keeps saying “harder” every time I ease up even a tiny bit during sex. It’s annoying asf that I’m fucking her hard already and she keeps saying harder. I get that it’s sex and hearing harder from a chick is normal but trust me, this frequency is abnormal.

I hit the gym pretty regularly so my stamina is definitely not lacking but I don’t have infinite stamina to be going balls deep hard asf for 30 minutes straight. This behavior started happening much more recently and never happened the first half of my ltr.

Idk if relevant but she’s pretty petite and I’m just slightly above average in dick size.

How do I go about stopping this behavior or this is no big deal and I just let it continue
