exposure for hocd.

I'm suffering for hocd for 6 months now.I just want it to f*king go away,its the only thing I want at the moment.I was still able to do some rational thinking and sort out all the problems I'm having with my sexuality sexuality/topic198588.html#p2062620(if ya wanna see the topic) so all im asking is there any way that I can do exposure therapy at home? Any tricks for exposure?
