It seems a lot of people really, REALLY don't get what 'consent' means.

From the famous "not everybody needs to be asked prior to each insertion" to the student that (allegedly) thought he'd surprise his partner with some non consensual BDSM to that fucking song to almost every damn comment on any article by anyone that suggests that yes means yes; it seems people really have a problem understanding that before you have sex with someone, and that's every time you have sex with them, make sure they want to have sex with you. This goes for men, women, everyone. Whoever you are initiating sexytimes with, just make sure they are actually genuinely up for it. That's it. It's not hard. Really.

If you're still struggling, just imagine instead of initiating sex, you're making them a cup of tea.

You say "hey, would you like a cup of tea?" and they go "omg fuck yes, I would fucking LOVE a cup of tea! Thank you!" then you know they want a cup of tea.
