Taking Care of My Partner Like a Pro

I've been in a long-term relationship with my partner, Alex, who prefers to experience the nurturing side of our dynamic. It's not just about playtime; I genuinely take care of them as if they were relying on me for everything, cooking, personal care, even bedtime stories before lights out. We both agreed it would be beneficial and fun for them to step back into a more receptive role in certain scenarios, letting go of the daily stresses and responsibilities that come with adult life. I've been doing this for over two years now, and while it's rewarding, there are times when I feel like I need to set stronger boundaries or introduce new elements to keep things fresh. How do other couples maintain balance and excitement in such a dedicated setup? Is my approach typical within our community?
