When it comes to experiencing those things, would you want to experience them the first time with somebody else who is experiencing them the first time also? Is he willing to experience them with you, being your guide and mentor, enjoying you enjoying them which could bring more joy to your relationship?

The biggest question is kids. Is he willing to have more if you want the experience of having your own children. Are you ready to be an instant mom? You need to deal with this immediately before you go any farther in this relationship. Raising someone elses kids is a difficult task. And this just doesnt involve the kids. You have to coparent as well. How is his ex going to accept you as a step-parent to the children? you will have to parent these children with her for the remainder of this relationship and what all will be involved in that? coparenting can make or break a relationship.

you have a lot to think about. good luck
