How does one learn to do oral sex

Are you asking how your partner could be better at giving you oral or how you could be better at giving it?

Me be better

It helps by first learning human anatomy. Learning where the most sensitive parts are and learning what the other person likes and dislike are important

Practice and ask them what they enjoy.

I was watching videos to help because I’m a visual learner

I just did different things until I found out what he liked. Now when I give oral I hear a lot of oh f*ck.
