There’s a thread already about mixing the spray pheromones with oil…basically you would need to shake it before you applied it because the alcohol and oil would separate… https://pheromonetalk.com/t/olive-oil-alcohol-and-pheromones-in-a-bottle-cooking-up-love/6960
I don’t know diddly about Instant Sexiness, but if you’re looking to turn her on you might try mixing Pre-Release Dirty with massage oil, or maybe some of your TUTH, but keep it to very small doses at first since you never know how women will react to 'none. You don’t want her horny and crabby at the same time.
Or of course, you could just be upfront and tell her about your new toys, which is so much simpler…
