Hi Nez,
I don’t have too much to go on with your post, but from what I understand, you are currently in a relationship, and cuddling with someone else, yet view it as “casual”. I am wondering why you don’t want to cuddle with your significant other and choose this man instead. I think if I were the significant other and I saw my boyfriends head in another woman’s lap, I would feel betrayed. No, this is not casual. Any kind of touching is not casual. I do think you need to re-evaluate your current relationship, and find out what is making you unhappy to make you want to cuddle with another man. Just some thoughts.
