Messing around?

So my boyfriend and I are both 16, and we’re kinda just starting to mess around and explore stuff sexually. We’ve both been really really big on communicating and stop each other pretty frequently to make sure what we’re doing is okay. I trust him so completely but I’m still worried.

I’m not worried that he’s going to do anything I’m not comfortable with, or vice versa, because again, communication has been a big thing for us. I’m just worried that I’m going to mess something up during, and it’s really eating at me.

I’m having a lot of fun and I feel safe and loved during, but I just can’t shake the thought that I’m going to just do something wrong? I guess that’s the consequence of inexperience but it’s still not a great feeling.

Do y’all have any advice?
