PIED??? Sexting???Need help!!!!

Hi everyone!!!

so let me start by saying that I’ve never really had any sexual experience before apart from making out with a couple of girls until last week when I actually had sex for the first time. I took some time to get hard after she gave me oral and even needed some more stimulation. I did end up penetrating her but just for a little while since I lost my boner. I got introduced to nofap and started off with the challenge. Now I went about 5 days without any pmo and don’t even feel like doing any pmo and I also think I might be flatlining now because of symptoms like slight dry cough, no libido, mild flu like symptoms, some anxiety before going to bed. However I ended up sexting w my girlfriend today and actually did not need any stimulation to get it up however it did not stay for more than a minute after I stopped sexting. My question is is sexting your girl alright as long as you don’t relapse or do any sort of pmo and my other question is do I seem to have severe PIED???
Thanks all...
