Hello!
After reading your account twice, I feel your anxiety. I'm here to help! I'll give you a gentle hug from a distance to show you I care. You can also use the "butterfly stroke" – crossing your arms in front of your chest and gently and regularly patting yourself – to reduce your anxiety.
You say that you have a habit of thinking, which is to "worry" before a disaster strikes, worrying about the one thing you fear the most. This is a kind of catastrophic thinking. You have put this kind of catastrophic thinking into your romantic relationship. But here's the good news! You can change your thinking and your relationship will change too!
The good news is that you can change your catastrophic thinking! You can stop worrying about losing love, being abandoned, and the impact on your relationship with your current boyfriend.
You had sex with your ex-boyfriend in your first relationship, and now you feel tainted. But you know what? That's not true!
If your current boyfriend had a relationship with his ex-girlfriend, would you think he has a blemish? So this blemish is a definition you have given yourself.
I suspect that the root cause is that you don't feel good enough, that you are dissatisfied with yourself. I suspect that if you are not good enough, it means that you are not worthy of your current boyfriend, and that you feel unworthy in your current intimate relationship. But I also suspect that you are worthy of your current boyfriend! And you are worthy of a happy, intimate relationship.
You say that your current boyfriend is very good, both families approve, and you two love each other very much. You feel that this is a blessing from God, and you are especially lucky!
But you always feel unworthy. If your current boyfriend finds out about your past relationships and discovers the blemishes you yourself have identified, it will trigger more feelings of unworthiness in you and you will become even more inferior in the relationship.
You are absolutely thrilled in your current intimate relationship! Both partners take care of each other's emotions and value each other. You adore your current boyfriend, and I suspect you already have a feeling that you are not worthy of him. You don't want anything to increase your unworthiness, and I totally get it!
You love him, and he loves you! This is your current life experience, and you feel that it is a rare and happy one that you don't want to lose.
You learned that your current boyfriend and your ex's cousin have a mutual acquaintance, and suddenly an idea popped into your head: "If they have sex and he films it and then sends the videos to your current boyfriend, your happy world will be destroyed." I guess this is highly unlikely to happen. The most likely scenario is that you will continue to encounter other setbacks in your life in the future, some of which you can imagine and some of which you cannot.
Every couple has ups and downs, and that's okay! When you encounter an obstacle, or when you encounter an obstacle in your imagination, you have the power to choose how you respond. You can choose to belittle yourself and let the feeling that you are not good enough for your current boyfriend take over, making you constantly blame yourself, regret, and worry. Or, you can choose to see this as an opportunity to grow and learn.
In a relationship, it's important to maintain a certain degree of balance. However, you don't think you're good enough, and there is a sense of unworthiness. In your eyes, this means that you are in a low position in the relationship, and you are climbing up to him. So, how can you make this relationship last long?
An unequal relationship, a self-deprecating relationship, in which there is always a feeling of not being good enough for him. How long can the relationship last?
Absolutely! Solving the root problem—that you are dissatisfied with yourself and don't think you are good enough—is the fundamental solution to the problem of being trapped in a catastrophic thought loop in the future, with all the entanglement, anxiety, and fear that it brings.
You can contact a counselor and ask them to accompany you on your journey of exploring your subconscious and understanding yourself better. They will be there for you every step of the way as you work together to break free from the cycle of catastrophic thinking that causes you to become entangled, anxious, troubled, worried, and afraid.
The world and I love you, and you should love yourself too!

It's understandable to have these worries, but it sounds like you're putting a lot of stress on yourself over something that is highly unlikely. Focus on the positive aspects of your current relationship and trust in your partner.
You've already recognized that your ex had poor character, so it's important to remind yourself that he wouldn't have the power to affect your present life. Your current boyfriend loves you and has no reason to seek out such negative information.
Your fear seems to stem from past pain. It might help to talk with a therapist or counselor who can offer professional support and strategies to manage these intrusive thoughts and build confidence in your present relationship.
The scenario you're imagining is quite extreme and not very probable. Instead of focusing on what ifs, try grounding yourself in reality where you have a loving, trustworthy partner who cherishes you for who you are.
It's clear you value this new relationship deeply, which is wonderful. Channel that energy into enjoying the time you spend together rather than letting hypothetical fears overshadow the happiness you share.
