I feel that every time and i get butterflies in my belly everytime it happens to me
The area around the belly button, also known as the navel or umbilicus, contains many nerve endings that are connected to the central nervous system. These nerve endings can be very sensitive to touch, and some people may experience heightened sensitivity and arousal when this area is stimulated.
Additionally, the belly button is located in an erogenous zone of the body, which can be a source of sexual pleasure for some individuals. This can be due to the fact that the area around the belly button is in close proximity to other erogenous zones, such as the genitals and the nipples, and can create a pleasurable sensation when stimulated.
Respect Boundaries: Keep in mind that your best friend and your sister are individuals who have the right to make their own choices about their relationships. If they are indeed dating, they may have their reasons for keeping it private.
Support Your Sister: If your sister is involved in a potential relationship, offer her your support and guidance. Make sure she knows she can come to you if she needs advice or someone to talk to.
