Warning: Excellent Hugger; any sexually implicit touching is not intended in a sexual way
See how I said sexually implicit? I mean that I won't grab your junk but I may run my fingers through your hair or hug you in a very comfortable (though socially awkward) way.
The two are related. Basically I think that some forms of touching (like hugs) shouldn't be associated so strongly with sex or love, they can be used in non-sexual ways as a form of social interaction, just like waving or talking.
