I feel like I can answer this question not because we waited until marriage, because we didn't, but because we are the only people we have been with for anything sexual/kissing.

We met our first week of grade 10 and began dating at 15 years old. After a year of dating, we had sex when we were 16 almost 17. We were always safe (condoms, birth control). I remember the first time as it was not like in the movies but it wasn't horrible. A couple months before our wedding we chose to not have sex to make the wedding night more "special" - We failed. Lol but it didn't matter, after the wedding was all said and done we drove home, ate leftovers and had a (non sexual) shower together. We went and almost fell asleep on the couch, but then he remembered the bedroom and made us go, and there was rose petals and candles everywhere. So I put on some sexy lingerie, and it went from there. Lol It was fantastic even though we were utterly exhausted from the long day. I would of been fine sleeping on the couch together and having sex the next day!

We are now 27. We have been together 12 years, married for 4. We have a 2 year old child. We have never kissed anyone other than each other or engaged in any sexual activities other than with each other. We have spoken about if we felt like we "missed out" on the hook ups or experiencing other people, but we just never felt like it was necessary. I know we both have thought about it more out of curiosity but it's never anything we regret.

Our sex life is great. We aren't vanilla but we aren't extraordinarily kinky. We enjoy sex and we enjoy having sex with each other on a regular basis. So even though we didn't wait until marriage, we have only been with each other and have no regrets.

TL;DR: didn't want until marriage but have only been with each other sexually - no regrets.
