*Trigger: talking about sex*
My SO is too worried that one of my kids might be awake (Most of them ARE kids) and therefore
sex is very rare in the relationship.
Our rules are solid and final. Usually, it's sex with me only.
If there is to be any kissing or contact with the others,
A. They have to be over 18
B. They have to be healthy enough not to be repeating the abuse or an unhealthy pattern
(The lustier one turned out to be repeating abuse in my system, he felt uncomfortable with this too)
C. It has to be okay with both me and him and talked about way before hand
D. Obviously, it would have to be well thought out and actually wanted by the alter
So far, none of them have met the requirements.
Long story short, it doesn't happen.
He's very good at telling when they are awake and refuses any contact from them.
We're going through therapy and someday, a far time from now, it -may- happen,
but it'll be a long way off.
He's still their best friend and gives them plenty of hugs, if they're okay with it
and a kiss on the forehead if he's being sweet. Obviously, any touching at all, even hugs, has to be okay
with the alters first, so this usually happens between him and his buds

If there is sex with me
A. I have to be fully awake
B. I have to stop any contact if I feel triggered, scared, or hurt in any way
C. The kids can't be awake
D. We both have to be okay with it (He can't feel uncomfortable with the idea)
E. We have specific boundaries we can't cross, I had to learn what his boundaries were
It really has kept trauma from reoccurring and I have been getting better in this safe environment.
Needless to say it is a lot of work but I have no hard feelings towards him (Although it is frustrating sometimes)
and it's wonderful that he is so cautious with me.
His walls are slowly coming down as I get healthier.
In the end it's really up to you and him how you proceed, but I thought that writing out the model that
my boyfriend and I follow (which works) might help.
There are very good reasons why we follow these rules.
Sex is a very tricky thing when it comes to DID and we don't incorporate any possibly retraumatizing actions
or unhealthiness into our relationship.
Remember that alters under the age of 18 are actually still children, even if your body is still an adult.
They won't process it the same way you do, and a lot of the time they have made it their role, or their job,
when they should not be doing these things. Once they do some of their own self work they may find that
they did not enjoy their role or taught themselves to 'like' it but will prefer not to.
Just like real children, littles should not be involved with sex.
Kids have trouble telling the difference between sex and love, because the fine line has been mashed
by perpetrators that told lies when we were little.
There are very blurry lines when it comes to this so you'll have to figure it out.
Be sure to keep as open of communication as you can, it's very important.
Hoping the best for you!
