Awkward but grateful.

Hi!

So this may be a little strange but hear me out. I come from a culture where relationships are frowned upon. I have been with a girl before but whenever she'd go down on me, my little guy wouldn't cooperate.I just assumed I wasn't attracted to her and things didn't work out between us. I've been masturbating for as long as I remember. I'm 29 now and I think it started when I was 12. That's about 17 years of masturbation. I recently got engaged to a girl I'm attracted to but one I've done nothing with which is quite common in my culture. After our engagement we began some foreplay in the living room of her family home. This may seem like a lot of information but I want to be as detailed as possible. Again, my guy would be at half mast and go back down. I told her I was nervous as her family had been in the house. We facetime regularly and I was asked why my penis is never at full mast. I believe I suffer from PIED. I brought it up to her and she was completely understanding but at the same time I don't think she fully understands the need for rebooting. I'm on day 3 and it feels like a lifetime. I can get hard and orgasm within minutes of watching a video. I've shown her that. Now she sends me photos of herself and asks me to do the same. I wanted to know if this was allowed or should I go cold turkey until I feel like me and my johnson are once again on the same page. I can't remember the last time I've held a solid erection but at the same time I don't remember ever having to think about that with the availability of porn. I've read for some time the psychological reprogramming porn does to the brain but I swept it under the rug thinking everyone does it, why would it affect me. Now it's a bit too late but I'm thankful I have someone who understands. I just don't want to lose her over it. I'm committed to rebooting. Any tips or advice would be greatly appreciated. I'm so thankful for a forum like this.

Best,
Babcock
