Ok so you are asking something like whether my wife and I had any rules about sex with my alters.. no when I was integrated we did not set any rules like she could or could not have sex with my alters because she was involved with me the host.

no we did not have any such rules or boundaries. those that didnt want to have sex just didnt take control of the body during my wifes and my intimate moments.

my internal system of alters was one where everyone had their own way of being, their own thoughts, their own jobs with in the system and sometimes out in the real world too, and they had their own reason for being.

if their job, purpose, reason for being was not to take care of my intimate moments then they just did not take over control during those times.

I know some people who do make rules about all kinds of issues and are able to control who comes out when, where and why but that wasnt the way my internal system was.

I once asked my wife what she thought of my alters popping out to have sex with her.. she said "I love you, they are part of you, they came from you and they were all you the day you're mother gave birth to you. they are just extensions of you just like a normal person can like not just one form of sex. to me when Im having sex with those that want to, Im having sex with you because they are you and you are they."

now that I am one whole person again everything the alters were is once again part of me including the intimate moments. for my wife and I, it just added spice to our intimate moments and made us closer then ever.
