**TL;DR : Further background*\*
I've (26M) known my friend (25F) for almost 9 years. And there wasn't a hint of sexual innuendo all the time. And so, due to recent circumstances, we became very close and eventually decided that we were suitable for each other's relationship. We both perceive this relationship as our last, and that we will spend the rest of our lives together, which stressed her out when I proposed. And so, we meet. There is some tension due to the habit of being friends.
Against this background, I want to gain experience from those who have also entered into a relationship. Life hacks, questions, discussion, etc.))
