Bjs and Hjs

I’m nervous to give hand jobs and blow jobs. I tried giving one to my ex bf while we were dating and it didn’t feel right. I felt like I needed lube or something. Now that I’m with a guy who actually loves me and cares about me. I feel like it’s getting to that stage where things might get heated soon. I’m scared that when it gets to that moment that I won’t understand what to do. Last time I was too slow for him so I felt embarrassed and honestly upset. So I need tips on how to go faster and just all the tips in general. Help a sister out!
