Tampons 😡

Ok ladies. I need help. I'm 17 and wanting to switch over to tampons because they are way more convenient and I would like to use them while working out and all that. So a couple periods ago I tried to use one, but I couldn't figure it out or get it in because it hurt and tbh I didn't really know what I was doing. Well yesterday I explored a little bit before to try and figure out exactly where I needed to go and then I put the tampon in and it didn't hurt and it worked fine. But after that I could still kind of feel it. It didn't hurt at first but I could definitely feel it when I sat down and I hurt a little bit when I would move around while sitting. When I went to take it out again like 4 or 5 hours later, it hurt REALLY BAD and I had to force myself to pretty much yank it out, but a little gentler and it hurt really bad. I was scared to do it again today but I did and I had to find where to put it again and I put it in and I still feel it and it hurts a little when I sit. I tried pushing it further in but I think it's as far as it can go. I'm just scared about taking it out again and having it hurt like it did yesterday. I'm wondering if it's just not far enough in and how I'm supposed to get ut in further. Also did any of you experience this? Do you have any tips for me? From what I've read and heard you're not supposed to feel it, but I do. I'm just trying to figure this out so if you could help me out I'd appreciate it 😁
