I have been advised the 90 day rule before sex is a good principle to stick to. I know this varies between people and relationships. When does the 90 days start. Is it the first date or when you both agree not to see other people? Has anyone else found waiting 90 days helped? We have been dating for 6 weeks and official for 1 week. My man has said he will wait for however long it takes and that he wants me only. Surely you can do other sexual things during this period?
