Sex before marriage

So I grew up in an extremely Christian home and was told no sex until marriage. Well I didn't listen and starting having sex at 19. Now I'm 24 and still do and I enjoy it. I've had sex with 6 guys auys and 2 was/am in a committed relationship.  I still go to church and I do love God. But is sex outside of marriage really wrong?  All these were at different times. I have neve cheated or been the other woman. 4 of these guys were bad advice short term relational mistakes. 1 I was with for 3 years. We slept together we were planning a wedding and he dumped me. The other I'm now engage too. In no way do I cheat on anyone. You never play with someone's heart!
