Yes, they are something to definitely be concerned about...It shows that you have Hemorrhoids and your partner, being large, has pulled them out of your anus...Take some warm baths and soak them...Stay away from anal sex as you are asking for real trouble...If a man is too big it is possible, if he pulls out too fast, to do some real damage in pulling out part of your colon....If this continues, see your doctor...I am going to try and have this changed to the Hemorrhoids Forum...Good luck...

P.S. If you chance to do this again make sure you are very well lubricated....
