Its obvious there are differences in moral values that he does have a right to be concerned about. Yes, we alk have our pasts but those pasts if they havent changed can be red flags for the future.

Yes there are some things done in the past that we have learned from & wont do again & just because MANY in society do things doesnt make it the RIGHT THING TO DO.

Getting STD....obviously points to some level of being unsafe in your past though tou did the responsible thing NOW. Sexting...if you meet someone while with him....is it something you will do again?

He probably didnt think there was a reason to wonder about your past & wanted to trust that. He may be wondering if you really have values that he wants to continue wuth just as much as you are wondering.

Maybe your values arent compatible...might as well determine it NOW than wait until later with only more complications. Glad he apologized for the name/label calling. That isnt appropriate since he also has a past but there must be something about his past that he sees different than yours. That is what needs to be discussed to help determine if there really is a compatibility between you. Values do matter in a relationship if you really are interested in it becomming serious.
