Should I tell a person who is interested in me my sexual history?

So sad story, after my eight year relationship which was very abusive/ unhealthy. I became intimate with a friend who I used to advise about stuff he was going through. So one time when I wanted the intercouse stuff to stop, he forced his way after i was begging to stop...i started crying out of nowhere, and then he stopped and basically sent me an apology text when I got home. I was also found out he filmed me without permission when we were having a conversatio. I'm no longer in communication with the person but a girlfriend ( she was the one advising me to do stuff to get over my ex) basically told me I was assaulted.


Anyways, I think i finally found someone interested in me. And he is willing to call me often, etc. Basically all the stuff I have ever wanted. He is not experienced. He has had one sexual partner, relationship. And now I've had two partners now sadly and one relationship.

We agreed on transparency although we've never even held hands. But I want him to make up his mind about me so he doesn't feel cheated. I told him, I've had one relationship which is true but I didn’t think it was appropriate to go into the sex talk.

I have another girlfriend who advises against me telling any guy at all anything about me from past relationships.

So what's the best step here.....
