Blow job and vagina help!?!

So, me and my boyfriend have been together for a couple months now, we are both in our mid teens and have done some stuff (make out, given him a hand job and he has touched me 'down there' but over my underwear) All is well and good, but he would like a blow job (which I kind of want to give him) and he want to touch me 'down there' but under my underwear.

I want to give him a blow job, but all the thoughts about giving him one take over my mind like

"What if my teeth get in the way and I hurt him"

"What if it's not enjoyable for him and he's just putting up with it"

"What if he looks at me whilst I do it and I look weird"

This obviously gives me a lot of anxiety to give him one.

We talked today about doing more stuff and I told him how I was feeling about giving him one and he said that he wasn't going to love me any less if I did hurt him or if i did hurt him, yet I don't want to feel REALLY awkward doing it. Soooooo any Tip???

Secondly. About him going down my underwear with his hand.

I'm nervous because I can't get rid of all the hair "down there" and also, I have large labias which I think will disgust him a little bit

Help 😫
