I had it around my rectum when the psoriasis was at its worst but fortunately it cleared up after several months on Humira and then on Enbrel. It made receiving anal sex impossible for a long time. I was only able to perform oral sex when my desire for bisexual experiences was very high. Due to my spinal conditions of arthritis, stenosis, and nerve impingement it’s impossible for me to get in position to take enemas so my anal sexual experience is still very limited to those partners who are willing to give me an enema in preparation for it.

I had laser treatment in that area, and it helped a lot. I hope you get some help. Sorry.

If you already have psoriasis and now you have it some where else , it is possible to be there. Doctors either know or decided not to tell where actually this disease may attack.. Thats why they cant cure it.. I've had this problem before, but went away...
