hello everything where the partner is non-consenting is rape. the trope "I didn't agree to this but it feels so good I can't stop it" is still rape. The fact that they end up as couples is unrelated, as couples need to consent to things having being done to them as well, before they are actually done. Imagine one of these things happening to you.
let me point out SOME of the reasons why someone might not say stop when they are being raped (in other words engaged in sexual acts without their prior consent):
1. fear
2. confusion
3. humiliation
4. underestimation of how far things will go
5. who are you to determine whether or not they can say stop?
6. saying stop is not the same as saying "yes"
all stories involved rape or sexual harassment.... at least the partner in 32 year old virgin didnt do the same
