Ironically, it's bonding over shared interests and having fun together like this which is critical for a marriage. Doing things like this frequently is the glue that holds a relationship together, and is also necessary for getting couples in the mood for physical intimacy.
Even stuff like gardening together or taking a nature walk and chatting are great for this, as it's positive feeling, attachment, and trust that make it more likely that people will stay together and want to get physical. It's not obvious, but that's how human psychology and physiology work.
