Interesting that your MC stated you are "not a couple in crisis." I understand what he/she meant because C's have said the same about H and I. We have a pretty functional R, except for that darn SL issue.
We have a wonderful friendship and love and care for each other.
That is a wonderful foundation to a M.
We got back together after a 2 month sep but I did not tackle the fact I don't like sex.
Did the SL issues lead to the separation? I went through my own S with H and a lot of it had to do with that but mainly depression on H's end.
Glad to here you are in C.
You stated you have some low self-esteem. Are you depressed as well?
When you mentioned you didn't have any sexual fantasies I remembered my H said the same thing in one of our C sessions. MC said that was very rare. Some of it may be biological but largely social (I think).
You also mentioned thinking sex was "dirty." I think that supports the social control aspect of your LD. You will need to tackle that one if you want to shift your perceptions about sex long term. My H is having some success with this one so it can be done.
Keep posting. Lots of people will give you some great feedback and support.
