Which one is it? OCD maybe?

Okay. I wrote on here a few days back saying I was texting a girl and out of nowhere she sent a sexual text to me. Later she said that was her cousin, which was true. So as you may think, it spiked me and got me really horny. Then it seemed like my brain made an association between sex and texting. I now know you can't make an association off one text. SO I got really worried and have been obsessing for the past 3 days. Now it seems when I text two people in my phone I get hot flashes and nauseated. When I would text them I would be like "Do not think of the hot flashes. Do not make an association. Do not think of sex." And as you may think I thought of it anyway. When I text other people it does not do this. I know most of it is coming from obsessing because OCD can feel real and because the more I have been obsessing the worse it has got. It was not like this three days ago. And to you who don't know, OCD prospers on fear and worry. And that is what I was doing. I was fearing and worrying there will be associations made with these two people now it seems real. So what do I do to break the associations and do you guys think these associations with people I text are long term associations? Also I know some may think "Well you need to keep them out your life." That may be true but that means that porn is controlling me and who comes into my life. I will not allow porn to take people (especially close friends) out of my life. And even if I were to kick them out my life I will still obsess over the feeling I am having so it is a lose-lose situation. I really need help with this. Please. I am on day 18 of no MO and 3 weeks without porn btw. Something tells me to just stop obsessing, progress with the reboot and when I text them really enjoy and engage in the convo then everything should be back to normal. What do you guys think?

 

And I want to add that the person that sent the text is not the one I am making the association with now. It is two different people.
