Okay, so I found a slight problem during intimacy, my character is a heterosexual male who doesnt have a twat nor was his asshole penetrated, and well see for yourself.
I'm also getting this. My character is a Futa, but this occurs even when there has been no penetration at all. It will even occur if you enter sex and then immediately cancel - all involved parties will have the stretching notification.
It appears that many of the sex participant attribute initializations were lost or misplaced during the conversion to v1.0d. It will take quite a few detailed changes to fix, so it is not appropriate for posting here.
Awesome, thanks for the report! I happened to notice this last night as well and do have a fix for it that will drop in the hotfix coming soon that should resolve a lot of these last cosmetic tweaks.
