girlfriend kind of a sex fanatic

Just tell her about your worries, about your PMO addiction and may be about NoFap. That way she won't misinterpret your behavior. Talk about your attitudes towards sexuality in general. I am sure the two of you can find a solution together.

 

You are dealing with something that many of us in a relationship have.

Being that you are 20, I think there is a good chance that you can see results quicker. There is no absolute method you have to take to doing a reboot. The idea is simply to kick porn out of your life, and refrain from masturbation for a bit, and see what happens.

You can keep having sex, but.... it will be harder to know your success, and it may come with some challenges.

Everyone changes may come at a different rate based on their libido and health, and length of PMO use. (I'll share my scale, but yours may be very different) I'm 42 (43 later this year), and had mild-ED for perhaps 3 years, and delayed ejaculation all my life, and my scale included intercourse perhaps every 1.5 weeks (was doing PMO as a binge daily (multiple times per day for hours) for years, but in recent year, was 2 times a week (perhaps 3-4 hour sessions). I've found that a reboot of 2 weeks told me almost nothing (I had no faster erection/nor additional rigidity, and my orgasm/ejaculation wasn't anymore accessible to me). At 3 weeks, I found that I was a little quicker aroused, but it was easily lost, and my ejaculation wasn't any more possible.) At 4 weeks, I found I was quicker aroused, and through a lengthy vaginal session my ejaculation was possible (but that the GF could not 'take me'). I found that any PMO session immediately brought me back to day one. (I did that 5 months ago, and now doing another reboot at 34 days)

There are additional challenges. Every time you engage in sex, there can be a strong after effect which drives you to immediately have sex again. I've only recently encountered this, and wow! it's stronger than I imagined. Can really shake you from wanting to do partner sex only, and just go to an easy/immediate session with PMO.

So sex can be part of your recovery, and learning to relax and try things with your new exciting partner is a wonderful thing. Just as I would advise a woman though, make sure anything you do is your choice, and because your open to figuring out if you want to. Never engage in anything that you're uncomfortable with, and at any time during the session (yes during!) you have the right to say stop, back off, slow down! whatever you need.

Here is the thing, and why reminding you your choice is important. Turns out there can be many reasons for ED and for my situation of delayed ejaculation. Often this is medical. But most often when it isn't medical, there are emotional/psych reason we 'can't relax' enough to let the process take place. Sex is a balance between tension and relaxation.

A Nofap reboot can help restore you to the point your ready to experience that balance. It gives your body a chance to reset it's expectations, the mental images of porn to not be fresh and easily recalled, or your hormonal level a chance to recover from the possible impacts you've had from doing PMO to depletion. However, it doesn't guarantee that you will automatically 'relax' at the 90 day mark, or that 90 days is a magic number that 'everything just works'. Instead it's designed to give you a chance to understand what your sexuality function might be without the constant masturbation and porn.

Just be prepared, that when you are maintaining intimacy in your relationship that your results in that session may be less than what they would have been if you had first completed a reboot. (in short, maybe not the best time to experiment). And that your results wont be as obvious to you day to day, so it may be a little hard to process 'what's different', which might cause you to question why you can't have PMO (or if it had any impact at all).

Additionally, what to do to keep your GF happy? There is no right or wrong way to be intimate with your partner. You can do, or watch her do, whatever you feel comfortable with, and what she enjoys. There are many ideas here that are possible. It can be healthy and helpful to your relationship to be intimate, even if you don't seek orgasm as your goal, or feel at peak libido. There is a term that can be perceived offensively as 'maintenance sex'. It's often offensive because women in religion were told they should just submit to the desires of their husbands, no matter their feelings. You should absolutely never have sex when you don't want to. But the idea is that if you want to be close with your partner, because you feel connected, and want to share closeness with them, then you can do so, without pleasure as your goal. (Turns out that women have been doing this in long term relationships for years (and happy about it)) because they felt it strengthen their bond, and helped them feel engaged. I will stop short of giving you actual ideas for what to do, as there are many on these sites that anything sexual can tip them to want to break their reboot. (however, if you do want to discuss this, I would be open to answering questions in what my limited experience allows).
