The user, a 20-year-old woman (F20), began dating her boyfriend (M27) about six months ago, and they have been intimate for the last two months. For the user, this relationship involves many “firsts,” as he is only the second person she has slept with overall and the first she has slept with repeatedly.
During their first sexual experience, the user experienced significant pain, cramping, and deep stomach pain lasting several hours. This continued in subsequent encounters, prompting a doctor’s visit. The doctor found no diagnosable issue but suggested more foreplay or noted a potential size incompatibility between the partners. When the user shared this information, the boyfriend reacted by becoming flattered and repeatedly bragging about his size, refusing to change their intimate technique despite repeated requests because it consistently caused her pain. This led to a major argument when the user snapped during sex due to the pain and confronted him about his ego, making her now question if she was wrong for her reaction.

AITAH for snapping on my bf when he wouldn’t stop bragging about his “size”?



















In the field of relational dynamics, Dr. Dakota Bennett is known for noting, “Authentic intimacy requires mutual vulnerability, but when one partner weaponizes a physical attribute to assert dominance or deflate the other’s experience, the foundation of trust erodes rapidly.”
The boyfriend’s reaction to the doctor’s comments—interpreting information about potential size incompatibility as a compliment rather than a call for modification—indicates a significant lack of empathy and an over-investment in his self-image related to sexual performance. When the OP communicates that sex is consistently painful, this moves beyond simple incompatibility and becomes an issue of boundary violation. True sexual compatibility is not just about physical fit; it requires a willingness from both partners to adjust technique, pace, and preparation to ensure mutual pleasure and safety. His consistent refusal to change after being told it hurts constitutes willful disregard for her well-being.
The OP’s reaction, while intense, appears to be a stress response to sustained physical pain and emotional invalidation. While slamming the bathroom door might not be the ideal conflict resolution, her underlying frustration is valid. A path forward requires the OP to firmly re-establish that her physical safety outweighs his ego validation. If he cannot prioritize her comfort over his pride after this confrontation, the relationship is unlikely to become sexually satisfying or emotionally healthy for her.
THIS STORY SHOOK THE INTERNET – AND REDDITORS DIDN’T HOLD BACK.

















The original poster (OP) is in a situation where her physical discomfort and pain during sex are being dismissed or even celebrated by her boyfriend, who seems overly proud of his physical size. The central conflict lies between the OP’s need for physical consideration, safety, and pleasure, and the boyfriend’s apparent need to validate his ego through bragging about the very characteristic that is causing her distress.
The core question is whether the OP was justified in reacting strongly to repeated physical pain that was being ignored or minimized by her partner’s inflated ego, or if her outburst was an overreaction to a situation that should have been handled with more gentle communication. The debate hinges on balancing the boyfriend’s perceived pride against the OP’s actual experience of physical harm and lack of enjoyment.
