Karen and Suzanne were at Karen's after their first real date when they started kissing on the couch. Suzanne gently pushed Karen onto her back and started to undo her clothing. Karen felt a little uncomfortable and eventually tried to withdraw Suzanne's hand and sit up. Suzanne forced herself on Karen and sexually assaulted her. Same sex rape is intercourse without consent that occurs between two people of the same sex.
Rape is used as a tool with which to oppress someone.
If you or your partner feels pressured, manipulated or intimidated, then you have not established explicit consent and any ensuring sexual activity is sexual assault. Consent is positive feedback, not the absence of negative feedback.
