Dear Ava,

your girlfriend doesn’t seem to respect you and your needs, e.g. to have sex only when you too are in the mood, but is focused only on her own needs. She doesn’t respect your boundaries either, e.g. by being cruel during sex when you clearly don’t want it, by calling you derogatory names which you also don’t like and have told her so, by laughing at your need for precaution and protecting your health. As Anita says, she’s being abusive, and you’re enduring behaviors that you shouldn’t be enduring.

As for personality change during sex, yes, it happens with quite a few people, specially people who haven’t worked through their subconscious material, e.g. their anger at their parents, and so they vent their anger at their partner during sex. Sex brings a lot of our “shadow” to the surface, which otherwise we suppress. You’re on the receiving end of your girlfriend’s unprocessed shadow… think about whether you want to endure that, or you want to set some boundaries and protect yourself.
