Uncomfortable

Hey so basically ive never had anything done to me before and I feel like I should at this point (im 15) and maybe try exploring and I’ve tried masturbating and it has been uncomfortable at one point I was able to do it for a few minutes then I got uncomfortable and stopped is it normal for me to feel like this I just feel like my body weird and not normal and I’m really insecure about down so any lad that’s tried I refused because I didn’t want them to see it
