24 years old guy here... I have some questions

Hi everyone,
I'm a 24 years old guy, had my first sex experience only last year. And to my surprise it was nothing compared to what I had in mind. My penis didn't get hard enough like when I'm masterbating, and therefore couldn't do PIV. At first I thought this was only because I was virgin and it was my first time, but later that year, I met with some other girls, and the thing happened again. So I started to convince myself that the problem was with the girls, and that they were inexperienced enough to make me feel pleasure. So I went and hired prostitues, I did it like 3 times and still my penis didn't get hard enough and sometimes not hard at all, and only then I started to worry. Last week, I did an erotic massage, and I did notice that I had a good erection, but in order to have that, I needed to think of porn scenes and imagine them. But although I had a good erection, the woman couldn't finish me.
Now, I found this site last week, and reading some articles here, I found out that I may be suffering of DGS due to loss of sensitivity, I also may have PIED/ED, because I need to think of porn to have an erection and sometimes not at all. And last but not least DE, because I never orgasm when I'm with a woman, even when I have the slightest erection.
Now, 2 days ago, I started my challenge of no PMO. Today is my third day, I'm also writing my progress on some blog website that I will share later this week. And all this because of the success stories I read here and it motivated me to take such step. I hope one day I will be cured of these symptoms and I will be able to finally have an extremely enjoyable sex. And of course be a role model for those who also suffer from the same things and to be a motivation for them as others were for me.

Until not long ago, I believed that each person is the slave of his own mind and desires. I'm on day #3 and I'm starting to think different. A person is not his mind only, it's his mind, soul and body.

Now before I end up this topic, I have some questions I would like to ask.
Does the PMO challenge also restricts having fun with someone?
Can I still surf dating sites where I might bump into pictures of naked woman?
Can I still flirt with women over text messages?
Does feeling horny counts as a relapse?

Thanks in advance. And may the the odds be in our favor.

 

Thanks

 

You're right. Thanks for the advice.
