Roommate sees me naked all the time

I like being naked at home. I'm not naked all the time, maybe like 50% of the time. When I go to the common areas, I usually put on a t-shirt or something (just one item of clothing). At times when I'm especially lazy, I just walk around naked. My roommate, who is male, is pretty chill with it and is used to seeing me partly or fully naked. Sometimes his gf comes over. At that time I am fully clothed (I always am when there are guests over)... but I really don't think she knows about the situation. It feels weird to ask my roommate.
