This recently started happening i always have unprotected sex witthe same partner nd recently i have been bleeding during sex what does this mean ?

Could be infection: There are several different things that can cause bleeding during sex. Infections like chlamydia, gonorrhea, yeast or bacterial vaginosis can cause the cervix to bleed easily. A cervical polyp, endometriosis or other cervical abnormalities could also be the cause. You should see your doctor.

Need eval: You need to check your hormone levels and a gyn exam to make sure.
