Hi painisgrowth,
In my experience porn is always less interesting the less horny you are. I find porn completely unarousing immediately after orgasm.
My loss of libido took two forms. Firstly I would take longer in between orgasms to regain any kind of interest or capability - 2-3 days was typical while two orgasms a day was normal for me before. Secondly, even when I managed to get aroused, it was a struggle. I would normally require a lot of manual stimulation, and as I mentioned, maintaining arousal was difficult. It wouldn’t take much to throw off my concentration and then all my arousal would be gone suddenly. By arousal I mean not so much my hardon as the sexual flush, heightened sexual desire, etc. It would be like someone snapped their fingers and went “you’re not turned on anymore” and suddenly I wouldn’t be. Maintaining arousal involved maintaining a constant level of stimulation. Using condoms was next to impossible as I couldn’t get this constant stimulation.
As far as penile numbness goes, in my experience the main thing determining penile sensitivity is level of arousal. If you’re really horny, your penis will be super sensitive, if you’re not horny it won’t be sensitive at all. So while I experienced some numbness, it was a symptom of my underlying lack of libido rather than a separate problem by itself. I think a lot of guys who are new to sexual dysfunction get this back to front - they think they can’t experience sexual pleasure because their penises are numb, but it’s the other way around. Penis sensitivity is mostly in your head. It took me a while to work this out when I started having problems.
Having said that, there are a couple of supplements which reliably decrease my penis sensitivity. Zinc, for instance, makes it easier for me to get hard but numbs my dick like crazy. Megadoses of vitamin C do it as well.
Substances that helped with my arousal/penis sensitivity:
Magnesium: This is good stuff and I think every guy with sexual problems should take it. It has a bunch of roles in the body, but one of them is (along with vitamin B6) converting l-tyrosine into l-dopa for conversion to dopamine. Dopamine is partially responsible for arousal. I supplement 200mg daily and bounce it to 500mg if I’m expecting sexual activity. Effects take 8 or more hours to notice.
Vitamin E: Not sure of the mechanism here, but sure it helps me out. I don’t supp it normally but take 750-1000 IU on days when I need it. Again, takes 8 hours to notice.
Mucuna pruriens extract: This plant contains l-dopa, a direct precursor to dopamine. It takes at least 24 hours for it to work for me, which suggests that it might be the prolactin suppression caused by the dopamine rise which is responsible, rather than the dopamine itself. I wouldn’t take this regularly as the body may respond by desensitising itself to dopamine. (That’s what I like about Sustain Alpha - by stimulating the body’s own androgen production systems, the body shouldn’t react by trying to counteract its effects).
GHB: Unfortunately this is illegal, but I had great results with it with an ex gf. Takes about 15 minutes to kick in and makes me pretty horny. Recently it hasn’t been working, but I think that’s because I have a poor batch, it being black market stuff. Analogs like GBL and 1,4-butanediol get sold as GHB and I think I have one of those now. If you take this, be really careful with dosage or you could kill yourself.
Then there’s Sustain, obviously.
I haven’t noticed any difference with my scrotum. I think my balls may be smaller than they used to be but I’m not really sure and even if they definitely were I couldn’t tell you when it happened.
By the way, as I said originally, it’s still early days and I might lose these benefits after a while. I can tell you that Sustain is not snake oil though. I’m like 90-95% sure this isn’t a placebo effect or anything like that because there are some objective things going on as well as subjective improvement. For instance, when I was younger, I would produce a lot of precum when I got aroused. That went away when my libido dropped, but now I’ve started taking Sustain I’m producing heaps of precum again.
