Am I weird?

hi ladies :) so when I get down to business when I'm alone, I feel like I'm weird for doing it a certain way! Girls always talk about fingering themselves and using "clitoral stimulation" but none of that works for me! what I have to do is tense my Kigel muscles and almost like hump my bed?? I can't make it sound any less awkward 😂! Whenever I do things with my bf, I always end up faking it because he just fingers me and so on like that. I'm afraid to tell him that that's almost the only way I can finish! Is there anyone else like me? Am I normal? (I'm 18 btw)
