Now what the hell is it exactly? We're told (and I can attest to this) that it's different from sexual arousal because (in my case at least) it never turns into an erection or even something that you might enjoy. However could it be related to porn? I know some people without porn addiction who also happen to suffer from OCD get the same groinal response, sometimes to non-sexual thoughts like harm or taboo. For me, the groinal response started when porn thoughts just creeped into my brain out of nowhere, but I didn't care because I knew I was aroused by porn anyway. That was until I started getting the groinal response to sexually horrific stuff like gay or incest, hence my OCD nightmare ever since then. Any thoughts guys?
