What does it mean when a guy holds the back of your neck while walking? Like going through a crowded place?

So this guy that I’m seeing (we date but don’t have sex since I’m a virgin) has done this a few times already. Instead of holding my hand or waist he grabs me by the back of my neck while walking behind me, he does this firmly (not abusively). Is this some time of neck fixation/sexual tension thing?
For what I’ve noticed he sometimes grabs me there firmly like massaging me or strongly enough to make me laugh (again, it’s not in an abusive way). Or also when checking something on my face he grabs me by the chin or cheeks firmly too, there’s always this tension when he does it or anything I mentioned.
I want to clarify the abusive thing because I know some people aren’t into this type of stuff or choking and similar things so if you are not into that try not to comment since you wouldn’t get it.
