Don't worry I'm good with women and I don't have any problems at all. I'd been in a relationship before without having sex and it was fine. If it wasn't due to religious purposes, I wouldn't hide it from you. At the end, our identities are private on this platform and I think most of the users find it easy to be honest when telling their stories.
Lucky you if you have time for women. I perfectly agree with no sex before marriage, because I'm a convinced christian practitioner, and as you did, I even had my relationships with girls. The dirtiest things I've done were masturbation with one of them, and I now realize that it was such a mistake of mine, but obviously her mistake too. She pretended to be like me, even with my religious morality, just for having me in check. Anyway, I don't wanna talk about her... It's sucha sad story and I was such a different guy. I left her 3 years ago, after 5 months of relationship, and I don't absolutely miss her. Now I'm 24, I started this journey and I have other problems in my life to take care of. Have a nice journey, and if you wanna talk - as a brother in faith - I'm at your disposition!
I'm in the same boat as you. Same age waiting for the same reason. We will just have to do NoFap and see how it affects us physically, mentally, and sexually. Also I would add spiritually. Trust in God and he will make things right
THIS is the main goal for us. Getting free from pornography and sins in general is the greatest way to gain (or to receive as a God's grace) the freedom to let him guide you through the path of life, day by day. That's the key of everything, because we can finally freely choose His love instead of all the rest.
