Is it normal for sex to hurt after having started doing it three weeks ago with my husband, even had a small amount of blood afterwards twice. ?

Painful intercourse: Yes, sex is often painful at first. It often takes some time for your body to adjust and be able to respond comfortably, but it will. Suggest using a personal lubricant and take it slow with penetration. You be the pace setter. If it hurts, back off a little. The blood may be from small tears, but could be from some irritability of your cervix, but see your doc if that persists.
