Why do I enjoy watching things about pregnancy?

I am 18 years old girl I am not pregnant nor I never have been. On YouTube I subscribe to lots of teen pregnant teens doing vlogs on there pregnancy and enjoy get to see them change during there pregnancy and see how there belly grows and what goes on in there lives and wait to see there vlogs with there baby's. I feel like I'm a part of there pregnancies.i also enjoy watching there excitement when there preparing for the baby to come i also TLC baby story and bring home baby and bring home multiples. Also if you doing teen pregnancy vlogs let me know your name and I will subscribe to you.
