Tampons

I’m 15 and I’ve had my period for 3 almost 4 years now and the whole time I’ve been using pads. I hate pads they smell so bad even if you change them within an hour or 3. I hate it, it feels like a diaper. I hate the feeling of blood coming out of my vagina. I want to use tampons but I’m scared of sticking stuff up there. Any tips? 😬
