me and my boyfriend haven't used protection in 2 and a half years

Me and my boyfriend (soon to be husband) have been together for almost 4 years now and have been sexually active for 3 of them. After 5 months of protected sex I wanted to see how it felt without it and it felt amazing so we decided not to have protected sex ever. I'm not condoning this or saying go try it. Me and him both lost our virginities to each other and are completely healthy. The funny part is that I haven't gotten pregnant at all.
