Stop smothering and crowding him with the 'tickle baths' etc. people need personal space and none of that is erotic or affectionate, nor is running 'around the room making crazy faces'. It's not kindergarten.
Get out of the rut of domestic drudgery and plan exciting interesting things. Get more involved outside of the relationship/home with friends, family, career, courses, classes, interests and hobbies. Volunteer, join some groups and clubs. Get in shape and update your clothes, hair, look etc. be out of the house much more on your own.
Whether you stay together or part ways becoming your own person and toning down the high-school behavior with help any relationship you're in. Learn to be a responsible, yet loving partner.
