Fingering, well

So, I’m 14 and I play with my clit around twice a day. I’ve fingered myself a handful of times because it hurts to force my finger in there. I was with a guy and he was fingering me and it felt reallyyyy good. It just doesn’t feel good when I do it and I really enjoyed when he did it. It is just me? Is it the thrill of someone else? Advice on how to make it more enjoyable by myself?
