Can we do the thing that might also help - share what to advise the boys and let the girls know they've been told?
Ten off the top of my head:
1 Women and girls are human. People, with rights and feelings and dreams. Same as you are.
2 Women and girls are not domestic appliances; things to be bought, used, touched, discarded. See number 1.
3 Porn and prostitution are degrading to their frequently trafficked and abused usually female victims. 'Empowering sex work' is a LIE. See number 2.
4 Women and girls are generally physically not as big, strong or powerful as you. Yes, you could probably overpower most. But - don't.
5 Women's experience of sex will be different to yours. Unlike you, they will live with a monthly cycle that will affect their attitude to it. It can go from ohhhh yes please to get away from me in the happiest relationship. And that's her right.
6 Unlike you, they will go through pregnancy, childbirth, post partum experiences you can never share - and it will mean sex with you and centring you will not be as it was before. Are you ready to be a father? To step up and share this?
7 Get used to hearing and accepting No with grace. No to your demands for her attention, time, presence, smile, information, politeness, conversation, accessibility, compliance, acquiescence, submission.
8 You aren't doing the household things; the washing up / laundry / night feed / laundry etc 'for her'. It isn't her job, her calling, duty, pleasure, hobby, domain. Don't require a thankyou.
9 Be able to see and not create more mess. Pick up, hang up, clear up and - apparently - wipe your arse.
10 Learn - LEARN - about menopause. There will be some changes round here.
