Sex with Extended family?

I missed this before:

Truly, I gave up on defining this subject as a whole for the species a long time ago.

Some people do well with monogomy, some don't. Personally, though, the people I've met who do well with it do not seem to be what I define as happy, and this used to cause me to question those around me. I had to realize, though, that my definition of happy is not necessarily everybody elses' definition.

Sure, people will always be territorial, but I have a habit of disregarding territorial boundaries and taking what I want when it comes to this particular topic.

Of course, while I understand that people are territotial, I don't really see why they are when it comes to those they have sex with. Just because that person has sex with someone else doesn't mean you can't anymore.

I guess I just don't view other people in the same way I view my property.

 

Look at it this way
You cannot talk/discuss/express 'certain' things with your brother, but it is quite ok with a brother-in-law.
Now you can do the same with anyone who is not your brother, but with BIL there is incredible sense of Trust, because he is not just anyone, he is your own sister's husband.
When I see my SIL or any SIL flirt or play naughty or discuss things openly with a BIL, I look at it this way only

However in some above posts, somebody had very explicitly made moves to have sexual activity with a BIL. It is clear they were desperate.
IMHO I would be nice to them, but than taking care of it in a short-term manner, I would rather be on their side to find a long-term solution
Doing something hot for the moment that leaves a bitter taste whole life is something you dont try with relationships

Even if it is a 3some venture with wife involved, I still think it is a dangerous game! Play such game with someone with no strings what so ever....
