Top and bottom vs Dom and sub

Excuse my ty writing 

I've seen a lot of people using these words to mean the same thing but they're different

We all know dominant and submissive

But lets look at Top and Bottom

These words started off as exclusive to ual encounters between two men, with the top being the one penetrating the bottom

To make it more inclusive, a top now means the giver and the bottom is the receiver 

So in lesbian relationships, if one girl prefers to touching the other over being touched themselves, they'd be the top, while if one prefers to be touched over touching, they'd be the bottom

Also top and bottom don't relate to physical position

If you're physically on top but bouncing on your partners , you're still the bottom 

As such, you can get Dom bottoms, sub tops, etc

Saying you're a bottom doesn't automatically mean your submissive

Also if your fine with both topping and bottomming, it's best to say your versatile rather than a switch 

Switch is easy to confuse with the Dom/sub/switch way of labelling while versatile is pretty much strictly for top/bottom/versatile
