As Westie said, you are way over thinking this. Pubic hair has been around since the beginning of time and so has oral sex. Do what you want to do with your pubic hair, if you want it natural then let it natural, it you want it trimmed or shaved then do it. If your b/f has a preference, I'm sure he'll tell you his preference and then you can decide what you want.
Dh doesn't care if I'm all natural, trimmed or shaved, he loves giving oral no matter how I am so I do what I want to do.
Whatever you decide to do, don't allow pubic hair to affect your sex life which you are doing. Sex is not about whether or not you have pubic hair, that shouldn't even be on your mind when you're being intimate with your guy.

It's been a long road getting from there to here.
I know the wind’s so cold, I’ve seen the darkest days.
But now the winds I feel, are only winds of change.
I've been thru the fire and I've been thru the rain,
But I'll be fine.
'Cause I've got faith of the heart. ---Rod Stewart
Sometime in your life you will go on a journey,
It will be the longest journey you have ever taken,
It is the journey to find yourself!
