Sexual postions and many other things

Heyy... i was wondering so its going on a yr for me and my bf im 2 months and i was wondering.

I give him blowjobs most time before sex but also just for him at times to i was wondering im a beginner but hes says Im REALLY good ive made him cum multiple times im his first blowjob too

I have trouble breathing and like i wanna know what is the best position for being able to breath better ? Or what can i do to help me breath better.?

He tends to make me go faster when hes gets close so i have more trouble lol id rlly like to learn more tricks n whatnot for blowjobs

Also me n him have been discussing on trying different moves during sex

What are some good moves that help me reach climax and feel good for him too?
