The idea of what is considered "normal" can vary depending on cultural norms, personal boundaries, and the nature of the friendship between individuals. Some people may feel comfortable changing clothes in front of close friends of any gender, while others may prefer more privacy.
It's important to recognize that comfort levels and boundaries around nudity and personal space can be different for each individual. What might be acceptable or normal in one friendship might not be in another.
If both individuals are comfortable with the situation and have established a level of trust and understanding, it may not be an issue for them. However, if either party feels uncomfortable or uneasy about such behavior, it's crucial to communicate openly and respectfully about their boundaries and preferences.
In any friendship or relationship, it's essential to respect each other's boundaries and communicate openly about what makes you feel comfortable or uncomfortable. If there are any concerns or discomfort regarding certain behaviors, it's best to address them honestly and find a solution that respects both parties' feelings and comfort levels.
