precum oozing out while talking to girlfriend on phone and physically.

my penis feels numb and precum oozes out of the penis all the time while talking to my GF on phone and the same when we meet.
i have stopped watching porn long ago. actually im planning to do my reboot with my girlfriend because im not understanding the concept of reboot. i feel like im in a reboot for some time which means i dont watch porn i dont fap. but i feel i should get intimate with a girl to rewire nerve firings, which is what im trying to do. BUt while im talking to my girlfriend on phone or meeting her, lot of precum comes out. is it ok or it just relapses you.

age 28 started masturbation late only unlike some accounts here they say age 8.. i started at age 14.. felt initial symptoms at 20-21 this affected confidence to get a girlfriend. i want to get married and settle down like all my friends. dont know will i ever be able to do that.
thanks i have found this site. please help me on this question.

I'll try put this as simply as I can.

Reboot: *No artificial stimulation* No porn sites, no bikini women on google, no searching facebook for attractive women etc. If it's not a real women it's harmful. So any time you look or search for any of these fake images you're not rebooting

Rewire: *Anything with a real women* Hugging watching movies, kissing, oral, sex, holding hands

Grey area: Masturbation and even sex to orgasm does slow down the process for a lot of people. You can have sex but stopping before you orgasm could be beneficial. Talking on the phone is not a relapse, but it might not be helpful. Precum is not a relapse.

I am aged 18 and have being watching porn and masturbating for the past 5years,I didn't know how it would affect me.I used to masturbate twice a week then after I got into a relationship with this wonderful girl things started to change,I started watching porn once in a while and masturbate once a week as everything was fine.
Our relationship is quite an active one.after some months I had started being a little intimate with my girl.I had noticed one thing everytime I hug,kiss and cuddle for too long with her,my penis would get hard quite alright and would get a huge amount of precum in my pant.after some time I would lose my strong erection into a semi-erect penis.this happened for the passed 6months now each time am with my girl.
This past few months we have being intimate with each other and reached an extact of oral sex.my penis would get hard but not 100% as I usually did.during oral sex it wud get semi-erect and when we ever I try to put have penetrative sex my erection is too weak to do the job of which I end being frustrated about.I have tried to have sex with her for two times and I end up having no erection at all when she even touches my penis all naked but nothing happens.its killing her inside and she complians about it.I have spent the whole day reading stories on this forum and I have decided to start rebooting today.if there is any help I would get upon stoping or reducing precum and having a strong and long lasting erection I will be very thankful...
