giving head for the first time?

okay so i’ve been dating my boyfriend for 9 months & i think i’d like to go down on him soon, but i don’t know how? like i obviously understand the basic concept, but like specific techniques? how do you make sure your teeth don’t touch him? what feels the best?

also, is it a problem if i have braces? like i can probably cover the brackets on the outside of my teeth with my lips but my problem is the way that i had to wear my rubber bands, my ortho had to put brackets on the inside of my top molars, which are very sharp. i don’t know how to keep him from touching those, because they kind of hurt my tongue when i touch them so i know they would hurt him. or i get them removed next august, should i just wait?

any ideas/tips/techniques would be very appreciate!!
