Do I NEED to give my boyfriends blowjobs?

I didn’t give my boyfriend a blow job today when he asked because I really was not in the mood too. Do I need to give them every time he asks? We’re only 17. I feel like I give him enough for my age. But when I don’t give them it makes me feel like a piece of shit girlfriend because I feel like I’m obligated to. I told him I was mad at myself and embarrassed that I didn’t. Idk what to do. I can’t stop crying.

I wasn’t talking on the way home because I literally had nothing to say. Not because I was mad at him but I’m a quiet person if there’s no conversation going on. He wasn’t talking either. And he doesn’t “beg” for blowjobs. I usually give him them when he asks

Also- I haven’t been able to have sex because of an infection for a little over a week which is obviously annoying for me too.
