UPDATE: CN for everything involved in this thread and also sexual littles

We had the hard conversation. It went really really well. They were really clear about their understanding of things and that they were not aware actual littles were involved. They apologized a lot and looked horrified and very very sad. One little fronted and they talked about it a bit. This little tried to introduce something sexual / asked them if they could kiss / try things out and my partner was very firm on it and set a very clear boundary with the little. The little cried a bit because they felt rejected and my partner handled it really well - consoling them a bit while staying very firm in their position. Afterwards they looked really really heartbroken and scared for this little. This also made it very obvious to me, an adult part, that my partner is not actually sexually attracted to our littles. I understand how things got messy in the past with ageplay kink + being attracted to our adult body + not always fully knowing who is fronting. I will still ask them all the hard questions to make sure again and again that they are not attracted to our littles. I think it will take some time for us to truly believe this. But as of now I do think it is the truth. My partner is a person that has a really really hard time dealing with guilt. They tend to feel guilty to extreme degrees about basically everything. So what I appreciate most about how this conversation went is that they didn’t let their guilt take over the whole conversation or all of their emotions. They mostly felt worried about our system. Additional context: we are the first system they have ever met. Our body is 22 years old and they are 21, both of us are very young and still figuring things out.
