Being Forthcoming about Past Sexual Sin

My partner and I F(19) M(23) have been dating for a month tomorrow, talking for around 3. We met on tinder and neither of us were particularly practicing and religious at the time due to our own issues, though I had a strong foundation in the church. We have really bonded over wanting to put God at the center of our relationship. We bible study and pray together and such. We also like to say that we are loving each other unconditionally and want - he is ill and it makes our entire process of dating very different and sometimes difficult. I know he’s extremely grateful for me being this and says he could never not want to be with me.

However, I know how he and men generally tend to feel & lose respect for women with higher body counts. When we first began talking though, he asked the body count question to which I wasn’t very honest because it was a stranger and I didn’t feel comfortable discussing past actions I find shame over. Last time we were together I confided in him about my past with being unfortunately sexually assaulted and hyper-sexualized all through my youth which contributed to my sexual behaviour. I gave him a number that matched his and was virtually half of what was true.

We both struggle/d with sexual sin, it’s not that I lied about my purity and he was a virgin himself - and I feel great amounts of guilt over it (I know this is not of God, I’m trying to work through it). I want to tell him the truth now that we have a very deep and honest bond, but I’m trying to balance the time for it being too soon or too late that it feels deceptive.

Should I open up about this tomorrow? It’s been on my heart but I feel it may be my own guilty conscience not God prompting me to be honest. Any advice is welcomed, shaming over my choices kindly is not :)

Thanks all!
