Receiving oral?

Okay so I have fears of receiving oral and I just want to know if they are normal and how to overcome them. My boyfriend really wants to try it but idk yet....

•isn't it awkward having someone's face around your junk?

•what if he doesn't like it but doesn't tell me bc he doesn't want to make me feel bad? (he likes to please me and make me feel good physically so that's something he would do)

•i have hair down there but I trim it, but idk why he'd want to put his mouth on that.... (Like ig I kinda gross myself out but I have self image problems so that explains that)

•what does it feel like?

•what do I do with the rest of my body? Lol

•am I supposed to clean down their with soap or a wipe or something?

Please respond to as many as you can lol I'm freaking myself out. Like I want to do it, but I'm a big time worrier. Lol sorry to overload with questions.
