Number of times

Me and my boyfriend have been together for a year and until the past few months I used to sleepover at his about once a week and when I did we would have sex more than 10 times over the two days (I would lose count how many times we did it)

Recently I’ve been seeing him more often than once a week (but still sometimes once a week) and now when i sleepover we have sex maybe 3 or 4 times over the course of the two days. It feels like quite a dramatic decrease to me and idk whether this is a good thing or a bad thing? Part of me feels kind of bad about it bc I feel like he doesn’t want to have sex with me as much but another part of me feels good about it bc it shows how our relationship has grown and now we don’t have to just have sex all the time. What do you think?
