Ammo seems pretty safe. You ought to ask Lor about the female perspective on Ammo (she sprays it on her pillow! search: Ammo pillow)
Keep in mind too much change may confuse her, and if she’s a religious person, and she feels herself burning with desire, like turn up the heat seems to do, she may just want to get out of the whole situation to avoid succumbing to her lust.

Try to gauge what your intended’s morals and social conditioning are.
If it is congruent with your perceived intent (altered by pheromones and environment), things should go well.
In other words, you might have a huge amount of ammo on and be with her alone, and she may freak out and leave you suddenly because her body’s reaction is scaring her, or you might have that same amount of ammo and be in a group and she’ll be all over you because she doesn’t think it will go too far. Depends on what she’s willing to do if “the circumstances are right.”
Personally, I’d lean more towards “Instant Honesty” or “Instant Female Magic” as a mix with Ammo OR Turn up the Heat. But not both together if I was going for a true lady. Which I am 
Just my viewpoint. The more viewpoints available, the better.
