Don’t feel like a dumbass! It was just your first post, and even though you made it clear you had been trying these things for a while, I think some people got a little overzealous in their instruction. 
It sounds to me as if you felt confident at that point to try your own combos, but now are feeling a bit self-conscious because of the smell comments, it didn’t work, etc.
When I don’t get the sort of reaction I expect from a combo, I take a step back and briefly re-evaluate each constituent and how they might be interacting with one another in ways perhaps I hadn’t thought of before. Briefly going over your combo:
8 drops EoW - alone, still not a lot based on your age. You said you waited 15 minutes for dry down and you didn’t notice a bad smell yourself. So far, no problems.
6 drops Primal Instinct - hmmmm. I’ve never used this before myself, but this is a product similar to Lust After Me, which is androstenol and cops. I’m not sure how concentrated PI is, but if I remember correctly it is a mix heavy on the cops. So you’re swimming in a lot of cops right now, but still nothing to worry about, imo.
3 sprays IS/b - we’re not exactly sure what is in IS/b except TAH and cops. It’s not a heavy cops product, but you’ve just added more.
3 sprays P83 - what’s the dosage?
3 sprays MX135 - 135 is a huge mix. Huge. It’s got everything: TAA TAF P79 TAH TAL androstenols and those are only the admitted ingredients. One thing that stands out to me here is that you’ve added P79. P79 in MX135 is great. It’s balanced in this mix and it works. Sometimes, though, if you add P79 to the wrong combo it can push things to the extreme. P79 can be very sexual on its own, even though mostly it’s characterised as an enhancer or extender. It’s like an addition that can make the one spray of something you’ve used give you the response of 3 sprays. You’ve also got TAF, a focuser.
So… EoW, Primal Instinct, IS/b. Cops, cops, cops. “I’m ready for some deep d!cking now”
P83. “Did I say now??? I meant now you $#@% what are you waiting for.*”
IS/b, MX135. TAH. You just stuck your finger in your mouth and made gooey cow eyes at your husband. After essentially telling him “Ah, push it. Push it good. Ah, push it. Push it real good!”
P79, TAF. You’re wearing a micro-mini shepherdesses’s costume and alternating between making humping/grunting noises and high-pitched little girl giggles while licking on a big swirly lollipop. Your husband inside was like this 
Do you do this normally? In public? You should be ashamed. 
I think what you got was extreme phero overload, pure and simple. Sometimes your targets are receiving such varied signals that they don’t know what to make of them, and hence… they make nothing of them. They are confused, but may not show it through any means but indifference.
Also keep in mind that the people around you on a daily basis are going to accept a new vibe from you very slowly. If they are good communicators, they might say something like “did you change your hair? Lose some weight? Did you change your makeup?” trying to pinpoint what is different. If they are not, or if they are doubting the new feelings they are getting from you, they may not say anything at all. They may not react at all until they’ve acclimated or “figured it out” (to whatever extent).
I think what you got was your phero baptism, which everyone does at one point or another. 
Every woman makes cops, all the time. They may be more potent at certain times of the month, one woman may not make as many as another, but they are always there.
but still a baptism. You’re doing FINE. You’re experimenting and having fun, and coming back for advice. That’s the best part!
