I read your answers about hymenoplasty but my case is specific, please help! I was 15 when I lost my virginity, stupid and naive- the guy was 10 years older than me so I changed my mind when it was about to happen, but he did it anyways. I was not a Muslim back then. Now I am a Muslima, 22 years old, shall I tell my fiance I did hymenoplasty, or does it count as my past (we shouldn’t talk about our previous sins; and Allah forgives the past, before islam and repentance). However, I feel like that big of a lie (deception) would cause a break of our relationship sooner or later and a heavier reason, I don’t want to stain my soul by lying! People nowadays underestimate what lies do to our character. On the other hand, I am very content I did it because it helps me guard from zina now. And it somehow healed me. May Allah bless you for your research and knowledge you share with us.
According to a fatwa by the Qatari Fatwa Authority, a person who committed zina should not tell the future spouse about it since the Prophet 
recommends that we do not tell others about our sins when God has allowed them to remain secret. This is also the opinion of Shaykh Muhammad al-Hasan al-Shanqiti in a fatwa. For this reason it may be best if you keep your history and your hymen reconstruction a secret. I understand the burden of feeling like you are living a lie. What you should do may change based on the character of your future spouse. If they are pious, open-minded and forgiving, then letting them know may not harm your relationship with them, while if they have some immaturity then it may be best to keep it a secret from them. It is a difficult choice, but as far as I know there is no easy way out. If you keep it a secret, you can make it up through repentance and worship, especially through developing a close relationship with the Quran through tahajjud and Quran-reading.
Best wishes inshaAllah.
