Bro, you may not have realised this, but your question can lead to problems.
AUS99 members have been singled out for moral criticism when they post their individual beliefs.

We had a thread recently where married people post honest opinions, and were then subjected to moral judgements by others
I found that a little unsettling

Im not married, so Im not being defensive here.

My 2 cents is that no man is answerable to another for a moral stance
People are answerable to their conscience, as well as their partner, the law, and their God (if they have one)

To answer your question, I would say...
'How would your partner react, if they were in the same room, when you do what you do ?'

But in contrast, I like this quote from a fellow AUS99 member recently:
Answering the question, 'How much money people spent on punting', he posted:

Roughly 19 years at $7,500 pa. Say $150 per week. It's only $143k.
First time I did the math the logic was inescapable ...
Punting is much much cheaper than divorce.

Another point. My best friend dated a Chinese lady who could only make love on top
Because of her slight body size and shape, she found all other positions very painful
On top, she would last 10 minutes, then that was it for her, tired but happy.
My friend tried to find other ways for sex, but all uncomfortable for her
She was a lovely lady, and had been married before
An interesting scenario hey ?
