Boyfriend won't buy condoms

My bf and I have not had sex in months because he refuses to buy condoms. Why don't I buy them you ask. I'm already on bc but I will not have sex without a condom because we're still young (19) and I don't want to risk anything. Plus, I bought them last time. I don't think it's my responsibility to buy condoms and be on bc. I'm on bc because of my period, I used to get really bad cramps so I didn't get on it for sex, I think of it as a plan B in case a condom breaks or something. Anyways, I've explained to him why I won't have sex without a condom, I've explained how him refusing to buy them makes me feel. It makes me feel unwanted because he's not putting the effort in. I can't withhold any other sexual transaction because I don't know how to not give him what he asks for. (Not in a bad way) I've asked him time and time again why he won't just go buy them and he said "I don't know" or "it's awkward." It's so frustrating. I just wanted someone else's opinion. Not really an opinion, I just needed to rant and need someone else to back me up.

Update: I gave up and bought them myself. I don't have a problem buying them, I just wanted him to take some responsibility. That was a couple days ago and we still haven't had sex because now I'm being petty. I'll probably give in soon though.
