In a relationship, people may feel shy or embarrassed about discussing certain bodily functions or personal habits with their partner. The example you gave, "am inside the toilet," is a lighthearted and humorous way to illustrate this common feeling of shyness when it comes to discussing bathroom activities.
Many individuals feel uncomfortable talking about bodily functions, such as using the toilet or passing gas, because these are typically considered private and not socially acceptable to discuss openly. Some people might also feel self-conscious about certain personal habits or quirks that they fear their partner might find unappealing.
However, as a relationship grows and deepens, couples often become more comfortable with each other and may gradually overcome these shyness barriers. Open communication and a sense of humor can help create a more relaxed and accepting atmosphere, allowing partners to share even the most trivial or potentially embarrassing aspects of their lives.
Remember that every relationship is unique, and the level of comfort with discussing certain topics varies from person to person. It's essential to respect each other's boundaries and be sensitive to each other's feelings while also nurturing a safe and open environment for communication. Building trust and understanding is key to creating a strong and healthy relationship.
