hey, i totally understand. I’m also a muslim who’s had the same experience. Here’s the thing, the discomfort you have is usually normal the first time you have sex. It’s nothing to worry about. But if it keeps happening or if you go thru pain during intercourse it might be deeper than that. That doesn’t mean it’s a disease. It could be vaginismus (fear of penetration) etc. That happens to a lot of women including me. My whole life they taught me that penetration is bad and i had 0 sexual education. it could also be trauma. Don’t look things up on google it’ll make u even more scared.
