Stroke. It's not safe and can cause trauma and more infection in uterus. .. And cause urine infection as well.
Hard strokes. It is a matter of degree. It can be painful and traumatic to have rough sex. This however would not cause a pregnancy if you are having safe sex. You should discuss with your husband that you are having pain or discomfort and to moderate the hard strokes. A frank discussion with your husband will be the most helpful to you.
