Is it normal to like the smell of your own period blood?
Yep.Totally normal
Yes, it’s normal to like or feel familiar with the smell of your own period blood. Menstrual blood can have a mild metallic smell, and noticing or liking it isn’t a problem by itself.
Period blood often smells a little metallic because it contains blood, and its scent can mix with sweat and normal vaginal fluids. You may simply find the familiar smell interesting or comforting; people have all kinds of sensory preferences, and this one isn’t something to be embarrassed about.
Smell can vary from cycle to cycle. If you notice a strong, persistent fishy or foul odor—especially along with itching, pain, or unusual discharge—it’s worth getting checked. Otherwise, liking the smell on its own is no cause for concern.
