Should sex be a fluid thing (no pun meant) with no set position, but a revolving search for mutual satisfaction?

I'm submissive , the males are always in charge . I always go along with their decision . How ever or whatever they want .

Domination

Im submissive

I'm the dominant person in the relationship, but good about it. I always make sure her needs are looked after. Sometimes sex is purely physical, in the moment, others it's a blend of need and sensuality.

Either fluid or submissive, here.

Fluid. I'm usually the dominant one, but sometimes she takes charge. Mutual satisfaction is always our goal and we usually achieve it, no matter what position or technique we use.

Depends on the mood your in but generally your gunna do your favourite position that give most pleasure or what’s the point in it if it’s not fun and satisfying

That's like asking what do you want to eat for the rest of your life ...

Fluid. Mutual pleasure should be at forefront not selfishishness.

It should be fluid, and not a rigid one. Both should have a say regarding position it depends on the mood and height of sexual feeling.

It should be fluid and depend on the time, the place, the mood. Sometimes you might want to make love, other times you might want to fuck.
