Hi,  I had intestinal surgery a year ago this month.  As of recently,  I started bleeding after anal sex.  I never had this problem before my surgery but now I do.  My husband and I would engage in it about once or twice a month during my monthly cycle and we've been doing this for about 19 years now. Also,  prior to my surgery,  it didn't hurt durning a session, now it does.  Once we're done,  it stops hurting of course,  but,  when I get up to use the bathroom,  I notice there's blood.  As I stated previously,  I didn't have this problem prior to my surgery. The doctors ended up cutting 4ft of my small intestine off.  I'm not sure if that has anything to do with it.  I also bleed afterwards  during regular vaginal sex.  In both instances,  the bleeding stops in the morning.  Again,  all of this started happening after I had my surgery.  What could be the cause?  I went to a GI Tract doctor and he said everything's fine.  I also went to  GYN and she said the same thing.
