I know we recommend the 3 month rule in relationships, but I was wondering if we should extend that even more. Like if I plan to get pregnant, I want to see if they will stay for 9 months with less sex/me looking less attractive. But then I think I want to take advantage of having sex for fun for myself during the honeymoon phase, which usually ends after 6 months, and I hear the peak feelings of relationships is usually at 4 months. Thoughts?
