wait the bruises are from sex?? if yes and you don't think your being to harsh with her then she does need to see a doctor, people who bruise easily have a medical condition. Bruising aside, it could also be painful for her if it's the first few times she has had sex. A curve in the penis should actually make sex easier, cuz the woman's insides are curved too. But yeah if the bleeding/bruising pain continue she really shoudl see a doc
