Based on my personal experience.
To start a romantic relationship in a serious way. The first thing we must do is to be honest with ourselves, accept our defects and virtues as well as our most hidden desires and fetishes in case we have them.The most important thing is to be honest and accept that a relationship based on good communication and real events is what we need as it is healthy. We cannot idealize, imagine, impose on someone who interests us everything that we like. There is no perfect person who fits all our tastes and desires so Let's be realistic and accept to know someone without prejudice, let's leave the hypocrisy and lies. Respect the time of people like me who really want to get to know someone well. In the end each person is responsible for their actions, their successes and failures as well as the consequences. Good luck for all of you.
