Sex isn't meant to be painful for women.

Sex isn't meant to be painful for women.
If something makes you feel uncomfortable or in pain, and the person you're having sex with doesn't care, that person is an asshole, and possibly a rapist.

Stop telling women that sex is supposed to be painful for them.
Stop telling women that they exist to fulfil men's desires and sexual appetite. 
Stop telling women to 'suck it up' and 'just do it.'

Women owe you nothing. They don't owe you pleasure, sex or anything else.
