These products should not "sting", the sensation you get from them (sprays, gels, balms) should be one of a tingling-spicy sensation like if you put toothpaste on your dick. So it stinging and the red spots are definitely not right, sounds you may be allergic to something in it?
Why not try another product, Edge Delay gel works very well as does Pau Yuen Tong balm. If you are really worried about "dodgy stuff from Amazon" (personally I have never had a problem with this stuff bought on Amazon, but that is my experience), go for the Edge gel, can be bought from your chemist. Use a tiny amount and rub into your frenelum, that plus the pills should see you right.
Well, may not be stingy but like you said, similar to putting toothpaste on your dick, obviously im not an idiot so i've never done it but I can imagine how that feels. It's not some insane stingy sensation, it's tolerable, however, the red spots aren't a good look. I've also noticed what seems to be small particles of skin that are white and last for days after showers, like when your skin on a finger peels a bit or something, so looks like it's abrassive or some sort of effect on there. The red spots take like 3 or 4 day to fully disappear. Im not using it again on the glans, like I said, I can only put it on the frenulum.
If I look at the ingredients it says this:
Each ml of solution contains 150 mg lidocaine and 50 mg prilocaine.
Each actuation delivers 50 microlitres which contains 7.5 mg lidocaine and 2.5 mg prilocaine.
1 dose is equal to 3 actuations.

So maybe I can pick something that only has lidocaine or prilocaine and hope one of these two are giving me the red spots and not both. You just can't show up with red spots, the girl would think it's a fucking std. And the red spot appears very fast, it's not like it happens hours after, like after 15 minutes i've seen it happen. Sometimes they aren't that noticeable and sometimes they show up faster. I was going to practice with summer with escorts using the spray at least on the frenulum but covid ruined it. I need real life practice and not just jerking around and doing kegels, that's just not enough in my case. Since im not rich I could only do it once a week with a good looking escort and hope I get acclimated to it and start picking up some fucking traction. Getting a gf now it's a waste of time with covid, I barely go out, and it's not like a civilian would tolerate some 30 yo that cums in seconds of a blowjob assuming I got that far. Would rather practice with good looking escorts for a while. If I can last with an 8/10 I would be able to last with 6/10 easier. It's just more realistic right now than trying to start a relationship with a girl. If I lived on my own perhaps it would be more realistic but right now im living with my mom saving a lot of money.
About the gel, I have no idea what that Edge thing is. Im in EU, sounds like an american thing, I haven't seen that there. There aren't any approved numbing stuff other than Fortacin in EU that I know off.
The Amazon stuff just makes me paranoid. Consider that you don't even know who you are buying from unless it's the official provider, and most of the stuff in Amazon is just chinese stuff rebranded. It's not the same as Fortacin which went throught actual clinical trials. I wish I didn't get these spots because it's at least promising compared to the rest i've tried.
What works extremely well is rub it across ur whole penis, pull up your underwear and leave it for like 2-3 hours, you'll feel a slight burning sensation wich indicates it's working. Do some kegels and you can actually feel if it's numb, you'll see your penis move but won't really feel it. Now go wash yourself and you're good to go. If your glands has a color difference it also works.
Yeah, i've considered putting it on the shaft too. My bottle has hit expiration date so im paranoid to use what's left, also it says that after 12 weeks of your first usage you should discard the remainers of the rest of the bottle. Not sure if there is a scientific explaination for this or is just a cash grab so keep buying new bottles.
The color difference is not a good look. You can't show up with red spots on your girl, again it may resemble an std for the girl and reject you, not a good view. I've tried leaving it 5 minutes only as suggested in the fortacin instructions and i've still gotten these damn spots so leaving it more time could just make it worse.
