I had sex (vaginal) with a man who has erectile curvature (downward) and since, i have been experiencing rectal bleeding. help?

Unlikely that major : See a colon rectal specialist to see if the bleeding is from haemorrhoids- shoild be an office fix.

?: It is unlikely that your rectum was injured significantly if you had regular activities. The vaginal wall is pretty thick/strong and not easily perforated with so-called normal activity.However if this persist i suggest seeing a doctor for an exam to find out the reason why.
