I found an interesting article that talks about a different kind of consent that what we normally think of and different than the one mentioned in "Yes means Yes." In "How to Say 'Yes!' to Sex (and not just 'OK only if you shut up about it')," Jacqueline Hellyer talks about how saying "Yes!" to sex in an enthusiastic and wholehearted way "is really saying “Yes!” to yourself as someone deserving of love, pleasure and adoration. Saying “Yes!” to sex is saying “Yes!” to love. It’s saying “Yes!” to life." I think that often times we let conservative and negative views on sex influence how we feel about it which in turn makes us ashamed to say "Yes!"
So, not only should we be more open to talking about sex, but the conversation needs to change to be something more empowering, uplifting, and real.
