Help please

I’m very young (14) teenager and my hormones are raging :/ I’ve had my period for about 4 years now and I started masterbating about 2 years ago. The problem is whenever I masturbate right after I feel dirty and disgusting with myself, like I’m less of a young woman. Does anyone have any advice to help me stop feeling this way? I know things like this are normal but i always feel guilty after I finish and it gets really upsetting. Help would be really really appreciated.
