Did you overcome it man ?
I started meds its really help to some degree....but I still get sensations in anus and mouth,but by far the worst is the false attraction,urges and impulses....oh a recommended read steven seays article on sexual obessions read it.Its a must read!!!!
yes unwanted thoughts which feel like urges are the part of ocd, these things will keep on continue until you take treatment for ocd.
so please take treatment for ocd from a psychiatrist and a psychologist. You can also take help from the book "Overcoming Obsessive Thoughts: How to Gain Control of Your OCD".
YES THIS ******* *****!!!
