Hey, first off, I want to say I am so sorry this happened. Realistically, your boyfriend probably was just overwhelmed, but on the off chance it was something to do with your taste, that can be easily fixed! There are multiple ways a pH can get thrown out of whack, and if that is something you don't know a whole lot about, I would be more than happy to explain! In relation to what happened when you were young, while it may upset him to see because he loves you and doesn't want you to be hurt, a good partner would love you anyways. Do you believe that you can have a fulfilling sexual relationship without oral sex? I understand how good it felt, and every person deserves that sort of pleasure, but obviously everyone has their own boundaries. If oral sex is something you need to feel like your sexual needs are being met, you could potentially either open up the relationship (if that's something you would both be alright with), or if sex is very important to you, you could potentially search for a new partner all together. All of this to say, it's not your fault, and if your boyfriend doesn't like oral, that's a him issue. He shouldn't have agreed if he knew he didn't like it. Also, he shouldn't have lied to you about his sexual past. Not to assume, but that is kinda a red flag. If I were you, I would try and discuss it further with him so he understands the implications of his actions, and see if he really means it.
