How to insert tampons? Please tell me your opinion

Okay, I'm fifteen and a virgin. So the thought of sticking something up my you know is a bit, eh. I want to start trying to use tampons but I'm nervous. I hear that you can't feel it unless you put it in wrong. I trust you guys' opinions so could you tell me like- uh- geez this is embarrassing. What to do? My mom was like "well you just put it in" talking to my sister (there was more but I don't remember.)  I don't want to ask my mom because it's embarrassing, so if you guys could please tell me. I've read that I should try using a mini one but my mom doesn't get those. 😳 Thank you for any info, I appreciate it very much.
