MX135 usually sneaks up on you. Especially when you are daydreaming.
I’ve experience the MX135 sudden horniness three times. Once when I first bought it with no cops, just driving minding my own business. Once when I made The I Need Sex Now Mix (The I Need Sex Now Mix) (has cops) and one more time when I used that mix on a particular individual. I let that mixture marinate in the heat and it actually killed it.
I think MX 135 on it’s own needs something else to relax you to heighten your arousal. But if you try to consciously capture the moment it never comes. Kind of like an orgasm I guess.
