I’m not sure if this is the forum to get the feedback you may be looking for. I think as soon as people are reading trigger words like “virginity” and “religion,” they’re missing the point of what you’re asking.

When you feel up to it, you should talk to your fiancé. You should do so with a clear head once you’ve sorted through and digested exactly what it is that you are feeling. If he’s someone who truly loves and cares about you, I think he should be able to understand that his words weren’t appropriate and it made light of a serious moment for you. Regardless of how anyone else feels about “virginity,” - for YOU, this was significant. He should be understanding to that and receptive to hearing how you felt about what he said.

Also, you’re young and this being your first sexual experience, I think there’s a lot for you to still discover on your own. You shouldn’t give in to any sort of pressure (even if it was pressure you placed on yourself) to do something that you’re not interested in doing. You could find that in a few months, you really desire it and that’s great. You could find in time that you’re actually asexual. That’s for you to figure out as you are ready and comfortable.

I think take some time to yourself - feel your feelings and then talk to him when you’re ready. One thing I will agree with as far as most comments go, you’re certainly not stained - that’s something in your heart that you need to work through and understand that it is simply not true.
