Frequent reaction to hot water in the shower at 24 weeks

I notice my baby always reacts to hot water when I’m in the shower. It’s like he gets startled and shifts every time the water is run over my stomach. I feel bad because personally I like the water on the hottest temperature it can be on, and that’s how I stay warm while I shower.

I have a removable shower head and maybe this is why I’m noticing with my 2nd this sudden movements because before with my 1st child she never moved abruptly like that when I showered since I didn’t have a removable shower head back then. Now I do have one and maybe the stream of water is more direct onto my abdomen as I guide it over stomach as opposed to the shower head just being stationary above my body.

I do lower the water temperature but that makes me feel cold and uncomfortable so idk what to do really. Has anyone experienced something like this and is it the water temperature causing him to startle or just the pelting of the water against the skin of my abdomen?
