don't allow this kind of violation to occur
if you can avoid, please do
if you can protect, always do
Because if you come across as easy.
The next level if your fren proceeds, would be at your own
cost.
Anything that constitude as uncomfortable/unwanted touches is
molest/harassment. You can take actions such as confront the person
if its intentional or since you know its outright, then that's the
end of your friendship. If possible, warn other frens. They might
actually share that they encounter the same thing.
BTW, there are more and more young perverts out there
nowadays...
Don't become a victim
