I am a 31 year old guy, I discovered sexuality by women near by place and hot shows in tv. My first M was a surprise but then gradually I developed a habit of MO in prone positions. Until recently I couldn't even use my hand for MO, which came with some practice. I used to MO using imagination at my boyhood days. In college I discovered porn, and soon after internet porn. I developed a fetish for hardcore stuff (gangbang, dominance, threesome, interracial) and eventually it turned out that is the only porn I am watching. I think since age 20-31 I am used PMO using hardcore stuff. Now I have a girl in my life since age 29, and we can't meet often due to being in long distance relationship. However when I first got a chance to have sex with her I realized I am not able to penetrate her for two reasons a) My erections are not hard enough for long time b) She is too tight (even for 1 finger) After several attempts of failed penetration the pressure and anxiety mounted on me. One major problem was each time we met maximum for few days, and then a long gap till the next meeting. So I felt it was making things weird. However at some point I decided to see a doctor. The doctor being a very commercial one, suggested me to go for PRP injection and circumcision. I have gone through a blood, hormone and seamen test, all being normal. The doctor gave me medications too for daily intake. Some supplements and some form of tadalafil. Again I took the medication for 20 days or so before I got a chance to meet her, where again the penetration attempt failed. I was like 80% hard, but that was not good enough. In the meantime my father in law (yes we also got married in between) came to know about the problem and gave me some homeopathic medicine (really supportive ), which I haven't consumed yet. I realized my problem of getting a strong 100% erection is due to porn. As the usual case of PIED, I have been exercising PMO for 10 years almost and it seems very plausible to me that my case is of PIED. Thats why all my tests are normal and the medication seems to be not doing great. I have most of the typical signatures of PIED. Also I used to super active in my younger days (ran marathon. climbed mountains) but now my lifestyle got very sedentary and gained lots of weight, that is also certainly a contributing reason in the whole problem. However I do believe the inability to penetrate also have to do with her tight vagina, and I guess we need to work on that before trying penetration next time. But for time being I decided to do something about my possible PIED. I am committing to the challenge of 90 days no-PMO. Today is the 5th day of the challenge, I found myself occasionally glancing at my go-to porn(pictures) but didnt go towards MO. I hope I can make it and in the process get the desired and enjoyable sex. I also stopped the medicine in my no-PMO phase, as I found myself one night unable to sleep well by thinking about porn after taking the medicine. I must commit my wife is very understanding, although she is getting upset and making me tensed (and loose my morale) time to time for a perfectly understandable. Still overall she is with me and willing to help me. I love her a lot, and I am committed to do whatever it takes to make her happy. As I said today is day 5 of my challenge, and I decided to journal my journey in order to stay motivated. Today is also day 4 of my challenge to get fit. I am 5'3'' and 86 kg now, my goal is to be 75 kg by December end (75 days from now) and continue with the no-PMO till then atleast. I commit to write my progress atleast once a week or whenever I fail.
