I need help in this situation

This is what he mentioned to me what do you guys think about the situation he claims it's a goal he's always wanted to do but I have mixed emotions about it and I'm not understanding what he's trying to say and I'm kinda feeling distant like he's getting annoying it might just be my hormones 🤦🏾‍♀️ thinking he's not attracted to me as much

We've never had any cheating problems or anything nothing! 🤷🏾‍♀️

we've been intimate and together for 6 years btw
