Am I wrong?

Am I wrong for not really being in the mood to do sexual things with my bf 24/7 like he is. I’m tired mentally and physically. I have a ton of school work I need to do and I really want to take a nap before I have to go to dance practice later. I don’t really want to give him head right now because I’m not in the mood. And plus I’ve never given it before and I’m scared to a little. Every time he asks I don’t really say anything and he says he’s sorry he sounds like he just wants sex right now and That he wants to cum too. Just because he’s made me cum a few times and I didn’t really repay the favor. Plus he’s asked me a million times when we’re “gonna fuck” and one I’m not ready because lately he’s been going through a rough patch which is understandable because so am I and I’m not on BC or anything yet and I’m really not supposed to have sex for a few months because I have to get my hpv protective shot. Do you think he’s going to leave me because I won’t have sex with him right now and because I won’t give him head? Am in the wrong? Please help me out
