Hi there,
So to be frank, I had pre-marital sex and developed a sexual dysfunction (constant desire). My relationship with the person in question, is nowhere. I now don't trust myself and feel very weak about things I should be strong about (the importance of a healthy relationship, God having part of that relationship, taking up my cross to defend that relationship). It is the Devil's doing, but sometimes (at least without talking about it) he seems to get every dart he wants to pierce my armour. I even learned to stay pure, since having that relationship, but I seem to struggle at both ends of the candle.
I don't know what you can do, what you can pray - but I did ask for prayer at a Church once and it seemed to help (just not completely, being on its own). Have you ever felt stuck, and the anxiety of being stuck just takes over? That's what it is like for me!
We'll laugh about it one day, but please - in the meantime - pray!
Love,
C
