ETA: if you really want a video i would suggest any of the Nina Hartley How To videos. Ms. Hartley is an awesome combo of ballsy, intelligent, sexual adventurous and entertaining. she manages to keep a video educational and hot. mostly cuz the participants are clearly like minded and enjoying themselves. also, very ladyfriend friendly.
you could let her watch you give a blowjob.
show her all the tricks you wish she'd do
for true. communication is the best foreplay/instruction manual going. positive feedback/vocalizations when she finds ya hot spots/does something ya like. ask her for what ya want. ya don't have to be clinical. just honest with what ya wanting from your blowjob experience.
porn seems to be a terrible place to pick up blowjob lessons. the boy is my first/only* interest in nekkid man time. what he likes/loves ain't nothing even close to porn blowjobs. i learned to rock his world by paying attention, hours of experimentation and straight up asking what he likes. asking him to guide me verbally and with hands.
was hot to learn. remains hot watching him get his happy on. will always be hot cuz being enthusiastic about it keeps me switching up my game.
* i mentioned first and only cuz for all i know the boy is a freak. what he likes might be penis oral*water*boarding to every other dude on the planet. the only thing i know for sure is the blowjob i see in straight porn = boy does not want.
ETA 2: curiosity, what does the MWM stand for?
