I don't mind it, it adds more depth to Emma's character. And it was pretty well executed. Sex scenes are way more engaging when you're into characters.
That said, I liked male character far more initially than in last two updates. He started off as decent, attractive guy placed in difficult situation, but he's now looking like another horny incel that can't control himself ( that you find in 95% of VNs here).
Their relationship/character development would be more interesting if both were reluctant and had more barriers to break as story progresses further ( so if MC had something like a loving wife, and Emma has issues with intimacy as result of her childhood traumatic experience).
