Tampons

I feel like I’m the only girl around me like at school and at home that doesn’t use tampons. Like whenever I see tampon applicators in the trash I feel embarrassed. I feel less female or less grown up for some reason. I don’t really have a need to use them but I feel like I should at least know how to. But, it scares me. The thought of putting a tampon in my vagina makes me uncomfortable and I always feel like I should know how to do this. I just don’t feel a need to. I’m 17 already and I feel like I should’ve done it already.
