One thing I knew about DID was what my treatment providers told me...

DID and having alters isnt something that just suddenly happens.

its something that happens to a very young child (here in my location the mental health statistics / demographices that treatment providers report to the government and state and county agencies is before the age of 5 due to extreme abuse / trauma)

Its also a situation where getting the diagnosis doesnt change what is and has been since very early childhood (my location before the age of 5)

that told me that even if I was ..............feeling............... what I thought was a new alternate personality. that alter really in reality was not new. They had been there all my life time taking control any time I had a problem and dissociated. even in therapy, out with friends or at home.

Another thing my treatment providers told me was that each alternate personality had their own sense of agency.

my point was when I felt like I had a sexual alter and this alter was new to me I contacted my treatment provider who told me yes Thelma was there and my treatment provider and Thelma had had many conversations around sexual issues. Why because that was Thelma's job, purpose, reason for being - to handle sexual situations.

in other words any time in my whole life since before the age of 5 where I had to deal with sex, intimacy I would have my dissociative symptoms and Thelma would take control and handle that, why because she was my sexual alter.

example ...

Any time my abusers abused me in any sexual ways I would dissociate (feel numb, space out, mentlally sink into what ever was around me and Thelma my alter whose sense of agency was to be and take are of sexual intimate situations would take control and do her sense of agency

in kindergarten when the teachers were explaining stranger danger, good touch bad touch and so on I would feel numb, space out, emotionally sink into the chair I was sitting on and Thelma would be the one sitting there in class learning about all this stuff.

in high school dating there was thelma doing her sense of agency any time this caused me to dissociate.

in school no matter when any sexual conversations came up I would dissociate and Thelma my sexual alter would handle that.

as an adult Thelma would take control any time I was in a dating, intimate situation.

my suggestion would be contact your treatment provider, or even your medical doctor. adults male and female have to periodically have their intimate parts examined in routine physicals, your medical doctor or therapist can look in their files and tell you whether they documented you dissociating during intimate, sexual conversations, physicals and such. they can also tell you details about this alter that they noticed or disclosed to them while you were dissociated and the sexual alter was in control. you can also check with your schools that you went to, they would have documented any time you were uncomfortable or dissociated during classroom discussions and any dating issues you may have had while attending their schools.

my point is there are many ways you can find out if this is just a feeling or whether there is a sexual alter there inside you and what to do next.
