The woman is clearly communicating her discomfort and lack of readiness. The boyfriend's persistence, despite her expressed feelings, constitutes undue pressure. She has the right to decide what she is comfortable with in her own body, and her boundaries should be respected without question.
While open communication is essential in a relationship, the boyfriend's repeated inquiries, framed as harmless curiosity, reek of manipulative persistence. He is prioritizing his desires over his partner's clear discomfort, effectively turning her body into a negotiation table. This isn't about exploration; it's about coercion.
The boyfriend is at fault here. The girlfriend has clearly stated her discomfort and lack of interest in anal sex. His continued inquiries constitute a violation of her boundaries and create undue pressure. While communication is important, it should not be used as a tool to wear down a partner's resistance.
