Very important.
Both ways
I got and gave oral long before I ever fucked. When I first fucked, I was disappointed. I really just wanted to get right back to the old routine.
Since ive gotten some better at fucking and grown to appreciate it too. But I´d take a BJ over a fuck anytime.
There is just so much more control, using your hands, tongue, lips, teeth, you can vary so much more than with your genitals, you can make the other person feel exactly what you want at any time.
