I feel so bad😭

I've been with my boyfriend for almost a year now, and he eats me out but i always feel bad because i never gave him a blowjob, like ever. I really want to give him one, but i dont know, im always scared to screw it up. I feel bad cause i know he wants one but i can never get the courage to do it.. I feel ready and everything, i just dont know why im scared to screw it up.
