I love making eye contact when giving oral to a partner, and most of my partners have specifically asked me to make eye contact with them while giving oral. I've found that it can be a little awkward or even uncomfortable to do so for long periods of time, so I'll generally just hold eye contact for about a minute at a time and just at random times throughout. Haha actually, I tend to move my head and neck a certain way when I look up, and my partners have sort of learned that as the signal for "Hey! I'm about to look up at you! Open your eyes!"
I love that moment when I look up and lock eyes with my guy; I absolutely adore oral sex, and seeing his facial expression, his eyes, his enjoyment when I'm giving that to him makes me feel incredibly sexy. Definitely
adds to the experience, in my opinion
