In my head

How do I get out of my head during sex? I recently started having sex with my boyfriend (he’s my first) and I just get so in my head every time. I worry about literally every movement, sound, smell, facial expression, etc. how can I stop focusing on these things and instead focus on the sensations and pleasure? And I don’t know if this would help, but I have always been someone who likes when people tell me what to do (kinda like a coach figure, encouraging me and teaching me). I know my partner isn’t my coach per se but idk maybe that kind of dynamic would help me relax a little and take some pressure off of me. What are y’all’s thoughts? and please don’t come at me about the coach thing, some people on here have been kinda judgy lately. I’m just trying to ask for some support.
