Any other Christians have an obsession that they will go against their values? I am so afraid I am going to start doing things other people do that are wrong in my beliefs

Every single time me and my boyfriend do anything sexual, I feel really really guilty about it after. We’ve never had sex before but have done other things and I don’t feel guilty about it in the moment, but afterwards I feel guilty. I don’t necessarily regret doing it but I just feel horrible as a human. He does not push himself on me in anyway and I know it’s all a me thing. He is very cautious in making sure I’m comfortable and feel okay, but I don’t start feeling guilty until afterwards. I feel like this always relates back to my faith, which has recently fallen off. I feel like I can’t talk to anyone about this because I always get told the benefits of waiting for marriage. And honestly I do understand that, but I don’t know that I want to wait. I feel like people keep shoving “waiting for marriage” down my throat and it draws me so much further from Christianity and makes things so much harder to feel close to God again. I just feel so lonely in feeling these things and scared I’m going to hell if I keep doing stuff with my boyfriend, but I genuinely don’t know what I believe in anymore and it’s draining me that my values are changing. I know it’s probably healthy and natural for values to change as you grow up, but I feel like there’s a stereotype of Christianity I have to adhere to and it makes me so anxious and scared I’m going to hell if I don’t get everything perfect. My relationship with Christ isn’t something that I involve others in because of how personal it is to me. But I just feel shamed upon by every other Christian and it makes me scared for myself and sad for the way society is making it such a black and white view of this religion.

I’m a Christian and I’m in my first relationship, often feeling guilty/uncomfortable with various things in relation to sexual purity. I’m struggling to know when things are OCD or genuine conviction. Any advice on how to know?

I have religious OCD and the thoughts have been becoming really bad. I’ve been hitting myself punching myself screaming quietly if that makes sense pulling my hair out talking to myself nonstop. I can’t even hang out with my family without doing these things or going to another room to do these things, these thoughts of overtaking my life I will always be Christian God is most important to me and I’m so scared because these thoughts are terrible. They’re disgusting they never ending. There’s always something going on in my mind. I don’t understand. I’m scared. I’m turning into a bad person. I don’t wanna dishonor the Lord God, I don’t know if this is just OCD or something else.
