Q:is it silly to want a DDlg relationship if i don't want to do sex kind of things yet? i know it's not the only part of that kind of dynamic.. but it seems like a bigger one than in vanilla relationships. i don't know if anyone is ever going to be interested in a little who doesn't like sex.. or if i even count as a little?
You can be an asexual little of course, but I would try to understand the basis of your dislike for sex. It is physical, is it mental, something else entirely? There are many medical issues, some that can shorten lifespans, that have symptoms that can look like asexuality or as I am translating from your ask, as a dislike for sex.
Asexuality is not unheard of, but it is very, very rare.
I am not saying you need to cure it, but I would recommend talking to a clinician about it certainly. It is a distinct possibility that there is NOTHING wrong, but that is a question you should answer so you can give the Doms you are interested in a complete and honest answer.
Hope this helps.
