Hey
@plumbus-nine
Basically, if a drug is what caused your problem, typically, removing the drug from the equation is going to lead to these effects dissipating. I know 3 months seems like a lot of time, but the sad truth is that these things often take a lot longer than people expect. Most medical literature regarding drugs, rather recreational or otherwise are going to focus on the acute, "observable" effects. That's what medicine is all about, observation and statistics. This makes the most sense if we're purely trying to keep a person alive and functional in our society. For instance, Opioid withdrawal ends when a person is able to pick themselves up off the bathroom floor, hold liquids down and regain control over their bodily functions. Again, this is all the easily observable stuff.
The effects of post-acute withdrawal are not discussed very often in medical literature, although there is more conversation being had over the last decade for reasons of the current Opioid epidemic. The symptoms are more vague, difficult to chart and hard for understand for someone not directly experiencing them. Situations like this are part of what has made Bluelight what it is today, as there was never really a good resource for this kind of information.
You more than likely just need more time man.
I've withdrawn from different things, as many of you know. Methadone was at least 6 months before I actually started becoming myself again. To put it in relevant terms for you OP, I would jerk off regularly at least 6 times a day until I basically had no fluids left in me. It was a long time before things started to change. In that time, there would've been little chance of me engaging with a woman in general due to my psychological symptoms, but it would have been pointless. I literally would've ejaculated by having a pretty girl touch my arm. I don't want to be too crass, but that's how it was for a long time. The point is, it did get better.
You are in a different situation. You already have a SO which needs you in different ways, including sexually.
The real deal is that lack of sex in a relationship between people (I've only ever been a man in a relationship with a woman, so I'm sure there is variability) is typically going to cause problems. Sex is just one part of a relationship, but in general, it is a very important part.
If you're SO wants to work on the problem, she is going to have to accept some kind of outside help. As it stands right now, you're unable to enjoy sex normally, but there are options for treating the situation. If you do enough reading, you will find that essentially any substance can be harmful in the appropriate dosage or in the appropriate body. Every drug is a poison in the right dosage.
As things go, Dextromethorphan (DXM) or (Robotussin) among many other names, is a pretty safe substance. In fact, it's a drug that the wider population probably has more experience with in general, as even non-drug users take Dextromethorphan when they get sick. As drugs go, it is one with a widely demonstrated safety profile, shown to be safe and non-toxic even in dosages higher than recommended on the box.
As all drugs are poisons, things get less-safe as you escalate the dosage. However, we're not implying you take a dissociative-level dosage of DXM. For me, even say, double the recommended dosage for an adult is enough to delay ejaculation significantly for me and I know plenty of other people who share this experience. I believe this is probably explained by the dissociative nature of the drug in general, which most describe as "being separated from their body" or "watching themselves move, but not being present"... that sort of thing. As drugs go, you have something here with a pretty favorable therapeutic index that might help you with a problem; a problem that could be life-changing if not addressed.
If you're SO wants to be able to enjoy sex, than you probably need to think out of the box. I would try having this discussion with them. If they're open to trying different remedies, then you can start by experimenting with relatively low doses of DXM. If that isn't effective, we can play it by ear and see what others have used. You're not the only person on BL to have experienced this problem.
