I'm confused. A red flag isn't something you dislike. A red flag is a warning sign (of abuse). Having a difference in preferences about cuddling isn't a red flag. And if someone enjoys cuddling more than you, it's not a red flag.

If they push boundaries, yes, that's a different thing. That's not what my OP was about, though.

I was referring to former abusers who had unusually high thresholds for touch, especially in the beginning, and who wanted a lot of skin to skin touch.

I was even thinking back to right after I realized I was in an abusive marriage, 6 years ago. I was so relieved to finally be rid of my husband and was feeling so happy; something I hadn't felt in a couple of years of being abused by him. We had to do an insurance thing, so I had to see him. He saw how happy I was and said, "It makes me want to touch you". I remember feeling utterly grossed out by the idea, but the point of my post was a contemplation about why he (and others) would want to touch. I'm hypothesizing that one reason is the endorphin release that biologically bonds people.
