Firstly, I know it’s easier said than done, but try to stop worrying. You’ve just made what is one of the biggest commitments in life and we live in a world where the media tries to convince us all that sex (a) is something we should all allow to rule our lives and (b) is only done ‘properly’ when performed by a couple with perfect bodies who end up snoozing the rest of the night away in an amazingly uncrumpled bed, with not a hair on their heads out of place and entwined in a snoozy embrace that would give any normal mortal being cramp after about 15 minutes!
I’m no theologian, but if you genuinely attempted intercourse and just couldn’t manage it through nerves and lack of experience, I can’t see how the fact that you enjoyed some foreplay beforehand is going to put you in a state of mortal sin if it was done specifically as a pre-cursor to penetration and with the intent of leading to full intercourse.
I know when I fist married, I found it pretty difficult to relax because for so long sex was sinful and then, literally, within 24 hours, it was fundamental to my married life: definitely a case of the spirit being willing, but the brain and flesh lagging a bit behind
One of the brilliant things about marriage (especially a marriage where you didn’t ‘try before you buy’ ) is that you’ve already built up a wonderful trust and respect for one another. It’s that genuine love and commitment that will eventually lead to a wonderful love life, because you’re working at it from within the sanctity and security of marriage.
It’s worth checking with a doctor in case your hymen is too tough to tear, or you could have a condition called vaginisimus, which is basically where the muscles all contract and is usually caused by stressing about the experience. Don’t be afraid or ashamed of sex though - you’r e a married woman now and you’ve every right to indulge and enjoy
