Sorry you're distressed from this ((SoupDragon)). Sorry I don't know your past history -do you know why you had this intense reaction? I would be uncomfortable with this considering he's basically a stranger.

To avoid this next time, I think you need to be comfortable with assertiveness - saying no compared to not saying anything and squirming inside. Remember it's your body and you can set boundaries. I hope you feel better and can get rid of this feeling.
