Sexting Induced Sexual Dysfunctions (ED)

I am 29 years old. I am a healthy, fit, successful individual who has been in great shape most of my 20's. over the last 3 years after my breakup I have dedicated my life to my career and haven't been going out too much. Since I had to fulfill my daily ejaculation needs I used to do sexting a lot which gave me unimaginable pleasure.

Over the last year I have realised I am having trouble first ejaculating with real life partners and then having penis go flaccid over the span of the sexual intercourse. This has happened now with three sex partners and over the last 6 months I have been battling NoFap.

I went on first NoFap on September 2020 and got rid of ED in only a month. I have obtained regular morning wood and got extremely hard many times per day. I masturbated twice, to which none were sexting. I had couple times sex (outstanding, hard, ejaculated quickly) without any problem. Then in late November I had sex and then masturbated the same day. Immediately after doing so I felt incredible shame and fear. From that point on I have been flatlining all the time. I have flirted with some girls over the instagram and that aroused me but i never continued to jerk off or anything.

I fear that even that little bit of arousal lead to the breaking the recovery. I have been on NoFap for 70 days now, where i had 5 days of semi hard morning wood and 5 days of hard morning wood and then periods of nothing again.

I don't want to engage in premature sexual intercourse with a woman not to break the cycle. I feel I shouldn't feel aroused at all and I am trying not to get a boner at all.

Do you guys feel that having a boner would compromise my recovery process? Is some flirting detrimental to my recovery if I get aroused? I am not watching porn at all. The problem is, trying to flirt with real life woman, is me hoping to have a new sexual partner when I get better.
