Thank you, MWM! I have been wondering the same. I thought it was clear that this is about consent.
Yet, there seems to be so much insecurity out there as regards what men are “allowed to do” nowadays. You just need to follow the Ansari story for example.
Intimacy is a two-way street. It requires consent. If small, sexual gestures work for you and your partner and they are a vital part of your relationship, then there is no problem whatsover.
If it only works for one of you, then there is.
