Condoms Hurt

Mariluna
I am a female who has never really had to use condoms before apart from a few times a very long time ago. I got an IUD in as soon as I became sexually active. Due to the IUD being a bit too large for my uterus and causing intense cramps literally all the time, I had it taken out. 
I'm considering getting the implant but for now I'm just on BC pills. It's been two days I've been on them, so we've been using condoms just to be safe. Every time they make my vag feel like someone's torching it. I feel a very intense burning and on top of that, I'm not able to orgasm like I usually can. 
Any explanations or advice would be appreciated. I don't know why this is happening!
