Pls help.

And what is happening...let's say I come across a video of that person and then I stop the part where it triggers me and I deliberately imagine images of a sexual type, and if I don't feel anything, I look again, as if I want it or I have the urge to imagine it, i.e. I feel the need, and if I feel something or get a feeling in my groin and I feel like I fall into despair?

Help please? I just feel idk..help ..
