That’s a great way to work and one I use a lot, not always with Ammo/IS then TUTH but the general principle and progression is much the same.
I tend to start a night/date/interaction with a more broad-based combination and Ammo/IS is just that - sexy/sociable/sound. Then as the evening goes-on, comfort, escalation and kino are developing and we move to a more determinedly sexual environment - eg a club, I will add-in some TUTH, then when we get home, I may well increase the overtness a bit more with some more TUTH and maybe something playful and pleasant - IS would fit the bill nicely here and a topup would be good as it won’t last as long as Ammo or TUTH.
However, if you are not getting clear indications of things developing in a sexual direction, do not introduce the TUTH as it will likely backfire on you.
Personally, I’m still skeptical until I see results. Being that I’m not going to judge a book by its cover, I’m giving it a shot. If it don’t work, I at least have decent cologne. If everything goes as planned, and this stuff actually works, around Christmas ill possibly introduce instant openness to my collection. This way it might open more doors on date.
