When to unpack the baggage?

After a five year relationship I’m finally putting myself back out there in the dating world, and I didn’t have luck for a long time but I recently reconnected with a wonderful man that treats me very well and we are taking things very slow. I just wanted to ask you ladies how long I should wait before getting into all of the bad stuff? It’s nothing that I need to disclose before being intimidate (STDs) but I definitely think it might change his opinion of me. My friends seem to think that I should put it off for a while to just enjoy now and have fun, but I would really be devastated if this got drawn out and then when I tell him later he won’t be interested in me anymore. Any thoughts on when the right time is to unpack the baggage?
