Wedding Night (the deed)

I am (27M) getting married this Summer. I am confident person generally speaking. But this part of life is hitting me as it is getting closer and closer. I am not comfortable speaking to my friends/family about it. Nevertheless, me and my fiancé openly talk about our wedding night. A lot of excitement of course. She is getting “tips” from her family and friends. But my problem is that I don’t feel comfortable speaking to mine about this. So this is where Reddit comes to the rescue!

There is an expectation that I am to lead the night and we have agreed on things that we want to do. But ultimately, as a guy I want to know what I need to do to prepare because I fear I won’t last. Are there any materials available to guide me? How did you guys feel? What are the expectations? Tips and help please? 🙏🏽
