I have seen a lot of posts recently about partners giving in to their partners, being intimidated or threatened into sex and not knowing if it's rape / assault because they didn't stop them / say no.
So I'm posting up this link about http://outofthefog.website/top-100-trait-blog/sexual-coercion and https://www.bustle.com/articles/67926-is-it-rape-if-you-say-yes-5-types-of-sexual-coercion-explained.
Keep safe and remember your happiness is just as important as theirs.
