When I first came to Thailand, I thought I Ka/Krap was based on the sex of the person I was speaking too and I thought this is how a Thai explained it too me.

Eg. If I was taking to a female, I would end with "Ka".

"Sawadee-Ka" "hello lady"

Taking to a male, I would end with "Krap"

"Sawadee-Krap" "hello sir"

But I noticed a lot of ....actually all females ending their sentences when talking to me with "Ka" (I'm a male)

So now I have the impression that I've been talking to females wrongly all along and that Ka/Krap is based on YOUR sex, not the person you are speaking too?

U should end your sentences with krup, as u are a man.

Krup can mean 'yes' as well.

Okay, thank you for clearing that up.

Can't believe I had been using this incorrectly, the most basic of learning Thai.

Ka/Krap is based on YOUR sex, not the person you are speaking too

That one. There are exceptions of course such as Ladyboy's will use Ka as it is the gender they feel they are. Some others are when joking or when talking to a child in order to teach them proper use.
