I feel like at the beginning the seme enjoyed making the uke squirm and he liked the control, but now that the uke is taking some control back and showing initiative, the seme doesn't know what to do. He's so used to being in control (probably in previous relationships too) or being the one initiating. Not saying this is a bad thing, just an observation
Or rather than enjoying being in control and not enjoying the uke's initiative, it's just that he's not used to it so he doesn't know how to respond, if that makes sense.
